|
|
Breaking changes: interface `MathNode` is now renamed to `MathNodeCommon`
|
|
and the related interfaces are structured in a different way.
|
|
|
|
- Fixed a typo in the TypeScript definition of toHTML. Thanks @TheToto.
|
|
|
|
|
|
# 2021-11-03, version 9.5.2`

|
|
see #2267. Thanks @davidtranhq.
|
|
- Fix #2269: `intersect` not returning `null` for matrix input. Thanks @m93a.
|
|
- Fix #2245: mathjs not working in IE11 anymore due to a missing polyfill for
|
|
`Symbol`. The browser bundle now includes the necessary polyfills (it is
|
|
larger now because of that, see also #2266). Thanks @m93a.
|
|
- Update dependencies (`complex.js@2.0.15`, `decimal.js@10.3.1`)
|
|
- Drop official support for node.js 10, which has reached end of life.
|
|
See #2258.

|
|
`@types/mathjs`, and making it easier to improve the definitions. See #2187,
|
|
#2192. Thanks @CatsMiaow.
|
|
- Upgraded dependencies
|
|
- `complex.js@2.0.13` (fixing #2211). Thanks @infusion

|
|
# 2021-04-12, version 9.3.2
|
|
|
|
- Fix #2169: mathjs requesting `@babel/runtime` dependency.

|
|
|
|
- Fix #2133: strongly improved the performance of `isPrime`, see #2139.
|
|
Thanks @Yaffle.
|
|

|
|
evaluating a non-existing function.
|
|
- Fix #660: expose internal functions `FunctionNode.onUndefinedFunction(name)`
|
|
and `SymbolNode.onUndefinedSymbol(name)`, allowing to override the behavior.
|
|
By default, an Error is thrown.
|
|
|
|
|
|
# 2021-03-10, version 9.3.0
|
|
|
|
- Implemented support for parsing non decimal numbers with radix point,
|
|
see #2122, #2121. Thanks @clnhlzmn.

|
|
|
|
# 2021-01-27, version 9.1.0
|
|
|
|
- Extended function `reshape` with support for a wildcard `-1` to automatically
|
|
calculate the remaining size, like `reshape([1, 2, 3, 4, 5, 6], [-1, 2])`
|
|
which will output `[[0, 1], [2, 3], [4, 5]]`. See #2075. Thanks @Josef37.
|
|
- Fix #2087: function `simplify` ignores second argument of `log`, for example
|
|
in `simplify('log(e, 9)')` . Thanks @quentintruong.
|
|
|
|
|
|
# 2021-01-16, version 9.0.0
|
|
|
|
- Improved support for bin, hex, and oct literals. See #1996. Thanks @clnhlzmn.
|
|
- **Breaking change**: parse literals with prefixes `0b`, `0c`, and `0x` are
|
|
now unsigned by default. To parse them as signed, you have to specify a
|
|
suffix specifying the word size such as `i16` or `i32`.
|
|
- Function `format` now supports more notations: `bin`, 'hex', and `oct`,
|
|
for example `format(255, {notation: "hex"})`.
|
|
- The functions `format`, `bin`, `hex`, `oct` now allow specifying a wordSize,
|
|
like `bin(10, 32)` and `format(10, {notation: "bin", wordSize: 32})`.
|
|
- BigNumber support for the bin, hex, and oct literals.
|
|
- Extended and improved the example rocket_trajectory_optimization.html.
|
|
Thanks @Josef37.
|
|
|
|

|
|
see #2024, #2041. Thanks @harrysarson.
|
|
|
|
|
|
# 2020-12-04, version 8.1.0
|
|
|
|
- Implemented units `kilogramforce` (`kgf`). Thanks @rnd-debug.
|
|

|
|
of MathJax. Thanks @pkra.
|
|
|
|
|
|
# 2020-11-06, version 8.0.0
|
|
|
|
!!! BE CAREFUL: BREAKING CHANGES !!!
|
|
|
|
- You can now use mathjs directly in node.js using ES modules without need for
|
|
a transpiler (see #1928, #1941, #1962).
|
|
Automatically loading either commonjs code or ES modules code is improved.
|
|
All generated code is moved under `/lib`: the browser bundle is moved from
|
|
`/dist` to `/lib/browser`, ES module files are moved to `/lib/esm`,
|
|
and commonjs files are moved to `/lib/cjs`. Thanks @GreenImp.
|
|
- Non-minified bundle `dist/math.js` is no longer provided. Either use the
|
|
minified bundle, or create a bundle yourself.
|
|
- Replaced random library `seed-random` with `seedrandom`, see #1955.
|
|
Thanks @poppinlp.
|
|
- Breaking changes in `pickRandom`, see #1990, #1976.
|
|
- Will no longer return the input matrix when the given number is greater
|
|
than the length of the provided possibles. Instead, the function always
|
|
returns results with the requested number of picks.
|
|
- Will now return a `Matrix` as output when input was a `Matrix`.
|
|
- Introduced a new syntax:
|
|
|
|
```
|
|
math.pickRandom(array, { weights, number, elementWise })
|
|
```
|
|
- Introduced a new option `elementWise`, which is `true` by default.
|
|
When setting `elementWise` to false, an array containing arrays will return
|
|
random pick of arrays instead of the elements inside of the nested arrays.
|
|
|
|
|
|
# 2020-11-02, version 7.6.0
|

|
|
|
|
|
|
# 2020-10-07, version 7.5.0
|
|
|
|

|
|
with 2 or more dimensions instead of only from a vector, see #1974.
|
|
Thanks @KonradLinkowski.
|
|
|
|
|
|
# 2020-10-07, version 7.4.0
|

|
|
more than two dimensions. Thanks @KonradLinkowski.
|
|

|
|
|
|
- Fix #1844: clarify the documentation of function `eigs`. Thanks @Lazersmoke.

|
|
|
|
!!! BE CAREFUL: BREAKING CHANGES !!!
|
|
|
|
### Most notable changes
|
|
|
|
1. Full support for **ES modules**. Support for tree-shaking out of the box.
|
|
|
|
Load all functions:
|
|
|
|
```js
|
|
import * as math from 'mathjs'
|
|
```
|
|
|
|
Use a few functions:
|
|
|
|
```js
|
|
import { add, multiply } from 'mathjs'
|
|
```
|
|
|
|
Load all functions with custom configuration:
|
|
|
|
```js
|
|
import { create, all } from 'mathjs'
|
|
const config = { number: 'BigNumber' }
|
|
const math = create(all, config)
|
|
```
|
|
|
|
Load a few functions with custom configuration:
|
|
|
|
```js
|
|
import { create, addDependencies, multiplyDependencies } from 'mathjs'
|
|
const config = { number: 'BigNumber' }
|
|
const { add, multiply } = create({
|
|
addDependencies,
|
|
multiplyDependencies
|
|
}, config)
|
|
```
|
|
|
|
2. Support for **lightweight, number-only** implementations of all functions:
|
|
|
|
```
|
|
import { add, multiply } from 'mathjs/number'
|
|
```
|
|
|
|
3. New **dependency injection** solution used under the hood.
|
|
|
|
|
|
### Breaking changes
|
|
|
|
- Node 6 is no longer supported.
|
|
|
|
- Functions `config` and `import` are not available anymore in the global
|
|
context:
|
|
|
|
```js
|
|
// v5
|
|
import * as mathjs from 'mathjs'
|
|
mathjs.config(...) // error in v6.0.0
|
|
mathjs.import(...) // error in v6.0.0
|
|
```
|
|
|
|
Instead, create your own mathjs instance and pass config and imports
|
|
there:
|
|
|
|
```js
|
|
// v6
|
|
import { create, all } from 'mathjs'
|
|
const config = { number: 'BigNumber' }
|
|
const mathjs = create(all, config)
|
|
mathjs.import(...)
|
|
```
|
|
|
|
- Renamed function `typeof` to `typeOf`, `var` to `variance`,
|
|
and `eval` to `evaluate`. (the old function names are reserved keywords
|
|
which can not be used as a variable name).
|
|
- Deprecated the `Matrix.storage` function. Use `math.matrix` instead to create
|
|
a matrix.
|
|
- Deprecated function `math.expression.parse`, use `math.parse` instead.
|
|
Was used before for example to customize supported characters by replacing
|
|
`math.parse.isAlpha`.
|
|
- Moved all classes like `math.type.Unit` and `math.expression.Parser` to
|
|
`math.Unit` and `math.Parser` respectively.
|
|
- Fixed #1428: transform iterating over replaced nodes. New behavior
|
|
is that it stops iterating when a node is replaced.
|
|
- Dropped support for renaming factory functions when importing them.
|
|
- Dropped fake BigNumber support of function `erf`.
|
|
- Removed all index.js files used to load specific functions instead of all, like:
|
|
|
|
```
|
|
// v5
|
|
// ... set up empty instance of mathjs, then load a set of functions:
|
|
math.import(require('mathjs/lib/function/arithmetic'))
|
|
```
|
|
|
|
Individual functions are now loaded simply like:
|
|
|
|
```js
|
|
// v6
|
|
import { add, multiply } from 'mathjs'
|
|
```
|
|
|
|
To set a specific configuration on the functions:
|
|
|
|
```js
|
|
// v6
|
|
import { create, addDependencies, multiplyDependencies } from 'mathjs'
|
|
const config = { number: 'BigNumber' }
|
|
const math = create({ addDependencies, multiplyDependencies }, config)
|
|
```
|
|
|
|
See example `advanced/custom_loading.js`.
|
|
|
|
- Updated the values of all physical units to their latest official values.
|
|
See #1529. Thanks @ericman314.

|
|

|
|
- Fix `math.simplify('add(2, 3)')` throwing an error.

|
|
|
|
|
# 2019-05-17, version 5.10.1

|
|
|
## 2018-02-25, version 4.0.0
|
|
|
|
!!! BE CAREFUL: BREAKING CHANGES !!!
|
|
|
|
Breaking changes (see also #682):
|
|
|
|
- **New expression compiler**
|
|
|
|
The compiler of the expression parser is replaced with one that doesn't use
|
|
`eval` internally. See #1019. This means:
|
|
|
|
- a slightly improved performance on most browsers.
|
|
- less risk of security exploits.
|
|
- the code of the new compiler is easier to understand, maintain, and debug.
|
|
|
|
Breaking change here: When using custom nodes in the expression parser,
|
|
the syntax of `_compile` has changed. This is an undocumented feature though.
|
|
|
|
- **Parsed expressions**
|
|
|
|
- The class `ConstantNode` is changed such that it just holds a value
|
|
instead of holding a stringified value and it's type.
|
|
`ConstantNode(valueStr, valueType`) is now `ConstantNode(value)`
|
|
Stringification uses `math.format`, which may result in differently
|
|
formatted numeric output.
|
|
|
|
- The constants `true`, `false`, `null`, `undefined`, `NaN`, `Infinity`,
|
|
and `uninitialized` are now parsed as ConstantNodes instead of
|
|
SymbolNodes in the expression parser. See #833.
|
|
|
|
- **Implicit multiplication**
|
|
|
|
- Changed the behavior of implicit multiplication to have higher
|
|
precedence than explicit multiplication and division, except in
|
|
a number of specific cases. This gives a more natural behavior
|
|
for implicit multiplications. For example `24h / 6h` now returns `4`,
|
|
whilst `1/2 kg` evaluates to `0.5 kg`. Thanks @ericman314. See: #792.
|
|
Detailed documentation: https://github.com/josdejong/mathjs/blob/v4/docs/expressions/syntax.md#implicit-multiplication.
|
|
|
|
- Immediately invoking a function returned by a function like `partialAdd(2)(3)`
|
|
is no longer supported, instead these expressions are evaluated as
|
|
an implicit multiplication `partialAdd(2) * (3)`. See #1035.
|
|
|
|
- **String formatting**
|
|
|
|
- In function `math.format`, the options `{exponential: {lower: number, upper: number}}`
|
|
(where `lower` and `upper` are values) are replaced with `{lowerExp: number, upperExp: number}`
|
|
(where `lowerExp` and `upperExp` are exponents). See #676. For example:
|
|
```js
|
|
math.format(2000, {exponential: {lower: 1e-2, upper: 1e2}})
|
|
```
|
|
is now:
|
|
```js
|
|
math.format(2000, {lowerExp: -2, upperExp: 2})
|
|
```
|
|
|
|
- In function `math.format`, the option `notation: 'fixed'` no longer rounds to
|
|
zero digits when no precision is specified: it leaves the digits as is.
|
|
See #676.
|
|
|
|
- **String comparison**
|
|
|
|
Changed the behavior of relational functions (`compare`, `equal`,
|
|
`equalScalar`, `larger`, `largerEq`, `smaller`, `smallerEq`, `unequal`)
|
|
to compare strings by their numeric value they contain instead of
|
|
alphabetically. This also impacts functions `deepEqual`, `sort`, `min`,
|
|
`max`, `median`, and `partitionSelect`. Use `compareNatural` if you
|
|
need to sort an array with text. See #680.
|
|
|
|
- **Angle units**
|
|
|
|
Changed `rad`, `deg`, and `grad` to have short prefixes,
|
|
and introduced `radian`, `degree`, and `gradian` and their plurals
|
|
having long prefixes. See #749.
|
|
|
|
- **Null**
|
|
|
|
- `null` is no longer implicitly casted to a number `0`, so input like
|
|
`math.add(2, null)` is no longer supported. See #830, #353.
|
|
|
|
- Dropped constant `uninitialized`, which was used to initialize
|
|
leave new entries undefined when resizing a matrix is removed.
|
|
Use `undefined` instead to indicate entries that are not explicitly
|
|
set. See #833.
|
|
|
|
- **New typed-function library**
|
|
|
|
- The `typed-function` library used to check the input types
|
|
of functions is completely rewritten and doesn't use `eval` under
|
|
the hood anymore. This means a reduced security risk, and easier
|
|
to debug code. The API is the same, but error messages may differ
|
|
a bit. Performance is comparable but may differ in specific
|
|
use cases and browsers.
|
|
|
|
Non breaking changes:
|
|
|
|
- Thanks to the new expression compiler and `typed-function` implementation,
|
|
mathjs doesn't use JavaScript's `eval` anymore under the hood.
|
|
This allows using mathjs in environments with security restrictions.
|
|
See #401.
|
|
- Implemented additional methods `isUnary()` and `isBinary()` on
|
|
`OperatorNode`. See #1025.
|
|
- Improved error messages for statistical functions.
|
|
- Upgraded devDependencies.
|
|
- Fixed #1014: `derivative` silently dropping additional arguments
|
|
from operator nodes with more than two arguments.
|
|
|
|
|
|
## 2018-02-07, version 3.20.2
|
|
|
|
- Upgraded to `typed-function@0.10.7` (bug-fix release).
|
|
- Fixed option `implicit` not being copied from an `OperatorNode`
|
|
when applying function `map`. Thanks @HarrySarson.
|
|
- Fixed #995: spaces and underscores not property being escaped
|
|
in `toTex()`. Thanks @FSMaxB.
|
|
|
|
|

## 2018-01-17, version 3.20.1
|
|
|
|
- Fixed #1018: `simplifyCore` failing in some cases with parentheses.
|
|

## 2018-01-14, version 3.20.0
|
|
|
|
- Implement support for 3 or more arguments for operators `+` and `*` in
|
|
`derivative`. Thanks @HarrySarson. See #1002.
|
|
- Fixed `simplify` evalution of `simplify` of functions with more than two
|
|
arguments wrongly: `simplify('f(x, y, z)') evaluated to `f(f(x, y), z)`
|
|
instead of `f(x, y, z)`. Thanks @joelhoover.
|
|
- Fixed `simplify` throwing an error in some cases when simplifying unknown
|
|
functions, for example `simplify('f(4)')`. Thanks @joelhoover.
|
|
- Fixed #1013: `simplify` wrongly simplifing some expressions containing unary
|
|
minus, like `0 - -x`. Thanks @joelhoover.
|
|
- Fixed an error in an example in the documentation of `xor`. Thanks @denisx.

|
|
- Fixed a security issue where forbidden properties like constructor could be
|
|
replaced by using unicode characters when creating an object. No known exploit,
|
|
but could possibly allow arbitrary code execution. Thanks Masato Kinugawa.

|
|
|
|
## 2017-10-18, version 3.16.5

|
## 2017-08-12, version 3.16.1
|
|
|
|

## 2016-03-04, version 3.0.0
|
|
|
|
### breaking changes
|
|
|
|
- More restricted support for implicit multiplication in the expression
|
|
parser: `(...)(...)` is now evaluated as a function invocation,
|
|
and `[...][...]` as a matrix subset.
|
|
- Matrix multiplication no longer squeezes scalar outputs to a scalar value,
|
|
but leaves them as they are: a vector or matrix containing a single value.
|
|
See #529.
|
|
- Assignments in the expression parser now return the assigned value rather
|
|
than the created or updated object (see #533). Example:
|
|
|
|
```
|
|
A = eye(3)
|
|
A[1,1] = 2 # this assignment now returns 2 instead of A
|
|
```
|
|
|
|
- Expression parser now supports objects. This involves a refactoring and
|
|
extension in expression nodes:
|
|
- Implemented new node `ObjectNode`.
|
|
- Refactored `AssignmentNode`, `UpdateNode`, and `IndexNode` are refactored
|
|
into `AccessorNode`, `AssignmentNode`, and `IndexNode` having a different API.
|
|
- Upgraded the used BigNumber library `decimal.js` to v5. Replaced the
|
|
trigonometric functions of math.js with those provided in decimal.js v5.
|
|
This can give slightly different behavior qua round-off errors.
|
|
- Replaced the internal `Complex.js` class with the `complex.js` library
|
|
created by @infusion.
|
|
- Entries in a matrix (typically numbers, BigNumbers, Units, etc) are now
|
|
considered immutable, they are no longer copied when performing operations on
|
|
the entries, improving performance.
|
|
- Implemented nearly equal comparison for relational functions (`equal`,
|
|
`larger`, `smaller`, etc.) when using BigNumbers.
|
|
- Changed the casing of the configuration options `matrix` (`Array` or `Matrix`)
|
|
and `number` (`number`, `BigNumber`, `Fraction`) such that they now match
|
|
the type returned by `math.typeof`. Wrong casing gives a console warning but
|
|
will still work.
|
|
- Changed the default config value for `epsilon` from `1e-14` to `1e-12`,
|
|
see #561.
|
|
|
|
### non-breaking changes
|
|
|
|
- Extended function `pow` to return the real root for cubic roots of negative
|
|
numbers. See #525, #482, #567.
|
|
- Implemented support for JSON objects in the expression parser and the
|
|
function `math.format`.
|
|
- Function `math.fraction` now supports `BigNumber`, and function
|
|
`math.bignumber` now supports `Fraction`.
|
|
- Expression parser now allows function and/or variable assignments inside
|
|
accessors and conditionals, like `A[x=2]` or `a > 2 ? b="ok" : b="fail"`.
|
|
- Command line interface:
|
|
- Outputs the variable name of assignments.
|
|
- Fixed not rounding BigNumbers to 14 digits like numbers.
|
|
- Fixed non-working autocompletion of user defined variables.
|
|
- Reorganized and extended docs, added docs on classes and more. Thanks @hgupta9.
|
|
- Added new units `acre`, `hectare`, `torr`, `bar`, `mmHg`, `mmH2O`, `cmH2O`,
|
|
and added new aliases `acres`, `hectares`, `sqfeet`, `sqyard`, `sqmile`,
|
|
`sqmiles`, `mmhg`, `mmh2o`, `cmh2o`. Thanks @hgupta9.
|
|
- Fixed a bug in the toString method of an IndexNode.
|
|
- Fixed angle units `deg`, `rad`, `grad`, `cycle`, `arcsec`, and `arcmin` not
|
|
being defined as BigNumbers when configuring to use BigNumbers.

|
|
- Fixed: added functions `math.sparse` and `math.index` to the reference docs,
|
|
they where missing.
|
|
- Fixed: removed memoization from `gamma` and `factorial` functions, this

|
|
- Adding two strings will no longer concatenate them, but will convert the
|
|
strings to numbers and add them.

|
|
instead accepts an array with arbitrary index values. It also accepts
|
|
a `Range` object as input.
|
|
- Function `typeof` no longer returns lower case names, but now returns lower
|
|
case names for primitives (like `number`, `boolean`, `string`), and
|
|
upper-camel-case for non-primitives (like `Array`, `Complex`, `Function`).
|
|
- Function `import` no longer supports a module name as argument. Instead,
|
|
modules can be loaded using require: `math.import(require('module-name'))`.
|
|
- Function `import` has a new option `silent` to ignore errors, and throws
|
|
errors on duplicates by default.

- Method `Node.compile()` no longer needs `math` to be passed as argument.
|
|
- Reintroduced method `Node.eval([scope])`.
|
|
- Function `sum` now returns zero when input is an empty array. Thanks @FSMAxB.
|
|

|
|
creation.

|
|
- Improved accuracy of `sinh` and complex `cos` and `sin`. Thanks @pavpanchekha.
|
|
- Renamed function `select` to `chain`. The old function `select` will remain
|
|
functional until math.js v2.0.
|
|
- Upgraded to decimal.js v4.0.1 (BigNumber library).
|
|
|
|
|
|
## 2014-11-22, version 1.1.1
|
|
|
|
- Fixed Unit divided by Number returning zero.
|
|
- Fixed BigNumber downgrading to Number for a negative base in `pow`.
|

|
|
|
|
|
|
## 2014-11-15, version 1.1.0
|
|
|
|
- Implemented functions `dot` (dot product), `cross` (cross product), and
|
|
`nthRoot`.
|
|
- Officially opened up the API of expression trees:
|
|
- Documented the API.
|
|
- Implemented recursive functions `clone`, `map`, `forEach`, `traverse`,
|
|
`transform`, and `filter` for expression trees.
|
|
- Parameter `index` in the callbacks of `map` and `forEach` are now cloned
|
|
for every callback.
|
|
- Some internal refactoring inside nodes to make the API consistent:
|
|
- Renamed `params` to `args` and vice versa to make things consistent.
|

|
|
- `FunctionNode` now has a `name: string` instead of a `symbol: SymbolNode`.
|
|
- Changed constructor of `RangeNode` to
|
|
`new RangeNode(start: Node, end: Node [, step: Node])`.
|
|
- Nodes for a `BlockNode` must now be passed via the constructor instead
|
|
of via a function `add`.
|
|
- Fixed `2e` giving a syntax error instead of being parsed as `2 * e`.
|
|
|
|
|
|
## 2014-09-12, version 1.0.1
|
|
|
|
- Disabled array notation for ranges in a matrix index in the expression parser
|
|
(it is confusing and redundant there).
|
|
- Fixed a regression in the build of function subset not being able to return
|
|
a scalar.
|
|
- Fixed some missing docs and broken links in the docs.
|
|
|
|
|
|
## 2014-09-04, version 1.0.0
|
|
|
|
- Implemented a function `filter(x, test)`.
|
|
- Removed `math.distribution` for now, needs some rethinking.
|
|
- `math.number` can convert units to numbers (requires a second argument)
|
|
- Fixed some precedence issues with the range and conversion operators.
|
|
- Fixed an zero-based issue when getting a matrix subset using an index
|
|
containing a matrix.
|
|
|
|
|
|
## 2014-08-21, version 0.27.0
|
|
|
|
- Implemented functions `sort(x [, compare])` and `flatten(x)`.
|
|
- Implemented support for `null` in all functions.
|
|
- Implemented support for "rawArgs" functions in the expression parser. Raw
|
|
functions are invoked with unevaluated parameters (nodes).
|
|
- Expressions in the expression parser can now be spread over multiple lines,
|
|
like '2 +\n3'.
|
|
- Changed default value of the option `wrap` of function `math.import` to false.
|
|
- Changed the default value for new entries in a resized matrix when to zero.
|
|
To leave new entries uninitialized, use the new constant `math.uninitialized`
|
|
as default value.
|
|
- Renamed transform property from `__transform__` to `transform`, and documented
|
|
the transform feature.
|
|
- Fixed a bug in `math.import` not applying options when passing a module name.
|
|
- A returned matrix subset is now only squeezed when the `index` consists of
|
|
scalar values, and no longer for ranges resolving into a single value.
|
|
|
|
|
|
## 2014-08-03, version 0.26.0
|
|
|
|
- A new instance of math.js can no longer be created like `math([options])`,
|
|
to prevent side effects from math being a function instead of an object.
|
|
Instead, use the function `math.create([options])` to create a new instance.
|
|
- Implemented `BigNumber` support for all constants: `pi`, `tau`, `e`, `phi`,
|
|
`E`, `LN2`, `LN10`, `LOG2E`, `LOG10E`, `PI`, `SQRT1_2`, and `SQRT2`.
|
|
- Implemented `BigNumber` support for functions `gcd`, `xgcd`, and `lcm`.
|
|
- Fixed function `gxcd` returning an Array when math.js was configured
|
|
as `{matrix: 'matrix'}`.
|
|
- Multi-line expressions now return a `ResultSet` instead of an `Array`.
|
|
- Implemented transforms (used right now to transform one-based indices to
|
|
zero-based for expressions).
|
|
- When used inside the expression parser, functions `concat`, `min`, `max`,
|
|
and `mean` expect an one-based dimension number.
|
|
- Functions `map` and `forEach` invoke the callback with one-based indices
|
|
when used from within the expression parser.
|
|
- When adding or removing dimensions when resizing a matrix, the dimensions
|
|
are added/removed from the inner side (right) instead of outer side (left).
|
|
- Improved index out of range errors.
|
|
- Fixed function `concat` not accepting a `BigNumber` for parameter `dim`.
|
|
- Function `squeeze` now squeezes both inner and outer singleton dimensions.
|
|
- Output of getting a matrix subset is not automatically squeezed anymore
|
|
except for scalar output.
|
|
- Renamed `FunctionNode` to `FunctionAssignmentNode`, and renamed `ParamsNode`
|
|
to `FunctionNode` for more clarity.
|
|
- Fixed broken auto completion in CLI.
|
|
- Some minor fixes.
|
|
|
|
|
|
## 2014-07-01, version 0.25.0
|
|
|
|
- The library now immediately returns a default instance of mathjs, there is
|
|
no need to instantiate math.js in a separate step unless one ones to set
|
|
configuration options:
|
|
|
|
// instead of:
|
|
var mathjs = require('mathjs'), // load math.js
|
|
math = mathjs(); // create an instance
|
|
|
|
// just do:
|
|
var math = require('mathjs');
|
|
- Implemented support for implicit multiplication, like `math.eval('2a', {a:3})`
|
|
and `math.eval('(2+3)(1-3)')`. This changes behavior of matrix indexes as
|
|
well: an expression like `[...][...]` is not evaluated as taking a subset of
|
|
the first matrix, but as an implicit multiplication of two matrices.
|
|
- Removed utility function `ifElse`. This function is redundant now the
|
|
expression parser has a conditional operator `a ? b : c`.
|
|
- Fixed a bug with multiplying a number with a temperature,
|
|
like `math.eval('10 * celsius')`.
|
|
- Fixed a bug with symbols having value `undefined` not being evaluated.
|
|
|
|
|
|
## 2014-06-20, version 0.24.1
|
|
|
|

|
|
- Functions `equal` and `unequal` support `null` and `undefined` now.
|
|
- Function `typeof` now recognizes regular expressions as well.
|
|
- Objects `Complex`, `Unit`, and `Help` now return their string representation
|
|
when calling `.valueOf()`.
|
|
- Changed the default number of significant digits for BigNumbers from 20 to 64.
|
|
- Changed the behavior of the conditional operator (a ? b : c) to lazy
|
|
evaluating.
|
|
- Fixed imported, wrapped functions not accepting `null` and `undefined` as
|
|
function arguments.
|
|
|
|
|
|
## 2014-06-10, version 0.23.0
|
|
|
|
- Renamed some functions (everything now has a logical, camel case name):
|
|
- Renamed functions `edivide`, `emultiply`, and `epow` to `dotDivide`,
|
|
`dotMultiply`, and `dotPow` respectively.
|
|
- Renamed functions `smallereq` and `largereq` to `smallerEq` and `largerEq`.
|
|
- Renamed function `unary` to `unaryMinus` and added support for strings.
|
|
- `end` is now a reserved keyword which cannot be used as function or symbol
|
|
name in the expression parser, and is not allowed in the scope against which
|
|
an expression is evaluated.
|
|
- Implemented function `unaryPlus` and unary plus operator.
|
|
- Implemented function `deepEqual` for matrix comparisons.
|
|
- Added constant `phi`, the golden ratio (`phi = 1.618...`).
|
|
- Added constant `version`, returning the version number of math.js as string.
|
|
- Added unit `drop` (`gtt`).
|
|
- Fixed not being able to load math.js using AMD/require.js.
|
|
- Changed signature of `math.parse(expr, nodes)` to `math.parse(expr, options)`
|
|
where `options: {nodes: Object.<String, Node>}`
|
|
- Removed matrix support from conditional function `ifElse`.
|
|
- Removed automatic assignment of expression results to variable `ans`.
|
|
This functionality can be restored by pre- or postprocessing every evaluation,
|
|
something like:
|
|
|
|
function evalWithAns (expr, scope) {
|
|
var ans = math.eval(expr, scope);
|
|
if (scope) {
|
|
scope.ans = ans;
|
|
}
|
|
return ans;
|
|
}
|
|
|
|
|

|
|
a Matrix as output.
|
|
|
|
|
|
## 2014-05-13, version 0.21.1
|
|
|
|

|
|
`math.parse` and `math.compile` instead.
|
|
- Fixed function `add` not adding strings and matrices element wise.
|
|
- Fixed parser not being able to evaluate an exponent followed by a unary minus
|
|
like `2^-3`, and a transpose followed by an index like `[3]'[1]`.
|
|
|
|
|
|
## 2014-04-24, version 0.21.0
|
|

|
|
Thanks Rogelio J. Baucells (@rjbaucells).
|
|

|
|
- Implemented `BigNumber` support for functions `det` and `diag`.
|
|
- Added unit alias `lbs` (pound mass).
|
|
- Changed configuration option `decimals` to `precision` (applies to BigNumbers
|
|
only).
|
|
- Fixed support for element-wise comparisons between a string and a matrix.
|
|
- Fixed: expression parser now trows IndexErrors with one-based indices instead
|
|
of zero-based.
|
|
- Minor bug fixes.
|
|
|
|
|
|

|
## 2014-01-18, version 0.18.0
|
|
|
|
- Changed matrix index notation of expression parser from round brackets to
|
|
square brackets, for example `A[1, 1:3]` instead of `A(1, 1:3)`.
|
|
- Removed need to use the `function` keyword for function assignments in the
|
|
expression parser, you can define a function now like `f(x) = x^2`.
|
|
- Implemented a compilation step in the expression parser: expressions are
|
|
compiled into JavaScript, giving much better performance (easily 10x as fast).
|
|
- Renamed unit conversion function and operator `in` to `to`. Operator `in` is
|
|
still available in the expression parser as an alias for `to`. Added unit
|
|
`in`, an abbreviation for `inch`. Thanks Elijah Insua (@tmpvar).
|
|
- Added plurals and aliases for units.
|
|
- Implemented an argument `includeEnd` for function `range` (false by default).
|
|
- Ranges in the expression parser now support big numbers.
|
|

|
|
- Fixed a bug with prefixes of units squared meter `m2` and cubic meter `m3`.
|
|
|
|
|
|
## 2013-12-12, version 0.17.0
|
|
|
|
- Renamed and flattened configuration settings:
|
|
- `number.defaultType` is now `number`.
|
|
- `number.precision` is now `decimals`.
|
|
- `matrix.defaultType` is now `matrix`.
|
|
- Function `multiply` now consistently outputs a complex number on complex input.

|
- Fixed `mod` and `in` not working as function (only as operator).
|
|
- Fixed support for old browsers (IE8 and older), compatible when using es5-shim.
|
|
- Fixed support for Java's ScriptEngine.
|
|
|
|
|
|
## 2013-11-28, version 0.16.0
|
|
|
|
- Implemented BigNumber support for arbitrary precision calculations.
|
|
Added settings `number.defaultType` and `number.precision` to configure
|
|
big numbers.
|
|
- Documentation is extended.
|
|
- Removed utility functions `isScalar`, `toScalar`, `isVector`, `toVector`
|
|
from `Matrix` and `Range`. Use `math.squeeze` and `math.size` instead.

|
|
retrieval/replacement of elements in a matrix.
|
|
- Implemented function `resize`, handling matrices, scalars, and strings.
|
|
- Functions `ones` and `zeros` now return an empty matrix instead of a
|
|
number 1 or 0 when no arguments are provided.
|
|
- Implemented functions `min` and `max` for `Range` and `Index`.
|
|
- Resizing matrices now leaves new elements undefined by default instead of
|
|
filling them with zeros. Function `resize` now has an extra optional
|
|
parameter `defaultValue`.
|
|
- Range operator `:` in expression parser has been given a higher precedence.
|
|
- Functions don't allow arguments of unknown type anymore.
|
|
- Options be set when constructing a math.js instance or using the new function
|
|
`config(options`. Options are no longer accessible via `math.options`.
|
|
- Renamed `scientific` notation to `exponential` in function `format`.
|
|
- Function `format` outputs exponential notation with positive exponents now
|
|
always with `+` sign, so outputs `2.1e+3` instead of `2.1e3`.
|
|
- Fixed function `squeeze` not being able squeeze into a scalar.
|
|
- Some fixes and performance improvements in the `resize` and `subset`
|
|
functions.
|

|
|
|
|
## 2013-10-26, version 0.15.0
|
|
|
|
- Math.js must be instantiated now, static calls are no longer supported. Usage:
|
|
- node.js: `var math = require('mathjs')();`
|
|
- browser: `var math = mathjs();`
|
|
- Implemented support for multiplying vectors with matrices.
|
|
- Improved number formatting:
|
|
- Function `format` now support various options: precision, different
|
|
notations (`fixed`, `scientific`, `auto`), and more.
|
|
- Numbers are no longer rounded to 5 digits by default when formatted.
|
|
- Implemented a function `format` for `Matrix`, `Complex`, `Unit`, `Range`,
|
|
and `Selector` to format using options.
|
|
- Function `format` does only stringify values now, and has a new parameter
|
|
`precision` to round to a specific number of digits.
|
|
- Removed option `math.options.precision`,
|
|
use `math.format(value [, precision])` instead.
|
|
- Fixed formatting numbers as scientific notation in some cases returning
|
|
a zero digit left from the decimal point. (like "0.33333e8" rather than
|
|
"3.3333e7"). Thanks @husayt.
|
|
- Implemented a function `print` to interpolate values in a template string,
|
|
this functionality was moved from the function `format`.
|
|
- Implemented statistics function `mean`. Thanks Guillermo Indalecio Fernandez
|
|
(@guillermobox).
|
|
- Extended and changed `max` and `min` for multi dimensional matrices: they now
|
|
return the maximum and minimum of the flattened array. An optional second
|
|
argument `dim` allows to calculate the `max` or `min` for specified dimension.
|
|
- Renamed option `math.options.matrix.default` to
|
|
`math.options.matrix.defaultType`.
|
|
- Removed support for comparing complex numbers in functions `smaller`,
|
|
`smallereq`, `larger`, `largereq`. Complex numbers cannot be ordered.
|
|
|
|
|
|
## 2013-10-08, version 0.14.0
|
|
|
|
- Introduced an option `math.options.matrix.default` which can have values
|
|
`matrix` (default) or `array`. This option is used by the functions `eye`,
|
|
`ones`, `range`, and `zeros`, to determine the type of matrix output.
|
|
- Getting a subset of a matrix will automatically squeeze the resulting subset,
|
|
setting a subset of a matrix will automatically unsqueeze the given subset.
|
|
- Removed concatenation of nested arrays in the expression parser.
|
|
You can now input nested arrays like in JavaScript. Matrices can be
|
|
concatenated using the function `concat`.
|
|
- The matrix syntax `[...]` in the expression parser now creates 1 dimensional
|
|
matrices by default. `math.eval('[1,2,3,4]')` returns a matrix with
|
|
size `[4]`, `math.eval('[1,2;3,4]')` returns a matrix with size `[2,2]`.
|
|
- Documentation is restructured and extended.
|
|
- Fixed non working operator `mod` (modulus operator).
|
|
|
|
|
|
## 2013-09-03, version 0.13.0
|
|
|
|
- Implemented support for booleans in all relevant functions.
|
|
- Implemented functions `map` and `forEach`. Thanks Sebastien Piquemal (@sebpic).
|
|
- All construction functions can be used to convert the type of variables,
|
|
also element-wise for all elements in an Array or Matrix.
|
|
- Changed matrix indexes of the expression parser to one-based with the
|
|
upper-bound included, similar to most math applications. Note that on a
|
|
JavaScript level, math.js uses zero-based indexes with excluded upper-bound.
|
|
- Removed support for scalars in the function `subset`, it now only supports
|
|
Array, Matrix, and String.
|
|
- Removed the functions `get` and `set` from a selector, they are a duplicate
|
|
of the function `subset`.
|
|
- Replaced functions `get` and `set` of `Matrix` with a single function
|
|
`subset`.
|
|
- Some moving around with code and namespaces:
|
|
- Renamed namespace `math.expr` to `math.expression` (contains Scope, Parser,
|
|
node objects).
|
|
- Renamed namespace `math.docs` to `math.expression.docs`.
|
|
- Moved `math.expr.Selector` to `math.chaining.Selector`.
|
|
- Fixed some edge cases in functions `lcm` and `xgcd`.
|
|
|
|
|
|
## 2013-08-22, version 0.12.1
|
|
|
|
- Fixed outdated version of README.md.
|
|
- Fixed a broken unit test.
|
|
|
|
|
|
## 2013-08-22, version 0.12.0
|
|
|
|
- Implemented functions `random([min, max])`, `randomInt([min, max])`,
|
|
`pickRandom(array)`. Thanks Sebastien Piquemal (@sebpic).
|
|
- Implemented function `distribution(name)`, generating a distribution object
|
|
with functions `random`, `randomInt`, `pickRandom` for different
|
|
distributions. Currently supporting `uniform` and `normal`.
|
|
- Changed the behavior of `range` to exclude the upper bound, so `range(1, 4)`
|
|
now returns `[1, 2, 3]` instead of `[1, 2, 3, 4]`.
|
|
- Changed the syntax of `range`, which is now `range(start, end [, step])`
|
|
instead of `range(start, [step, ] end)`.
|
|
- Changed the behavior of `ones` and `zeros` to geometric dimensions, for
|
|
example `ones(3)` returns a vector with length 3, filled with ones, and
|
|
`ones(3,3)` returns a 2D array with size [3, 3].
|
|
- Changed the return type of `ones` and `zeros`: they now return an Array when
|
|
arguments are Numbers or an Array, and returns a Matrix when the argument
|
|
is a Matrix.
|
|
- Change matrix index notation in parser from round brackets to square brackets,
|
|
for example `A[0, 0:3]`.
|
|
- Removed the feature introduced in v0.10.0 to automatically convert a complex
|
|
value with an imaginary part equal to zero to a number.
|
|
- Fixed zeros being formatted as null. Thanks @TimKraft.
|
|
|
|
|
|
## 2013-07-23, version 0.11.1
|
|
|
|
- Fixed missing development dependency
|
|
|
|
|
|
## 2013-07-23, version 0.11.0
|
|
|
|
- Changed math.js from one-based to zero-based indexes.
|
|
- Getting and setting matrix subset is now zero-based.
|
|
- The dimension argument in function `concat` is now zero-based.
|
|
- Improvements in the string output of function help.
|
|
- Added constants `true` and `false`.
|
|
- Added constructor function `boolean`.
|
|
- Fixed function `select` not accepting `0` as input.
|
|
Thanks Elijah Manor (@elijahmanor).
|
|
- Parser now supports multiple unary minus operators after each other.
|
|
- Fixed not accepting empty matrices like `[[], []]`.
|
|
- Some fixes in the end user documentation.
|
|
|
|
|
|
## 2013-07-08, version 0.10.0
|
|
|
|
- For complex calculations, all functions now automatically replace results
|
|
having an imaginary part of zero with a Number. (`2i * 2i` now returns a
|
|
Number `-4` instead of a Complex `-4 + 0i`).
|
|
- Implemented support for injecting custom node handlers in the parser. Can be
|
|
used for example to implement a node handler for plotting a graph.
|
|
- Implemented end user documentation and a new `help` function.
|
|
- Functions `size` and `squeeze` now return a Matrix instead of an Array as
|
|
output on Matrix input.
|
|
- Added a constant tau (2 * pi). Thanks Zak Zibrat (@palimpsests).
|
|
- Renamed function `unaryminus` to `unary`.
|
|
- Fixed a bug in determining node dependencies in function assignments.
|
|
|
|
|
|
## 2013-06-14, version 0.9.1
|
|
|
|
- Implemented element-wise functions and operators: `emultiply` (`x .* y`),
|
|
`edivide` (`x ./ y`), `epow` (`x .^ y`).
|
|
- Added constants `Infinity` and `NaN`.
|
|
- Removed support for Workspace to keep the library focused on its core task.
|
|
- Fixed a bug in the Complex constructor, not accepting NaN values.
|
|
- Fixed division by zero in case of pure complex values.
|
|
- Fixed a bug in function multiply multiplying a pure complex value with
|
|
Infinity.
|
|
|
|
|
|
## 2013-05-29, version 0.9.0
|
|
|
|
- Implemented function `math.parse(expr [,scope])`. Optional parameter scope can
|
|
be a plain JavaScript Object containing variables.
|
|
- Extended function `math.expr(expr [, scope])` with an additional parameter
|
|
`scope`, similar to `parse`. Example: `math.eval('x^a', {x:3, a:2});`.
|
|
- Implemented function `subset`, to get or set a subset from a matrix, string,
|
|
or other data types.
|
|
- Implemented construction functions number and string (mainly useful inside
|
|
the parser).
|
|
- Improved function `det`. Thanks Bryan Cuccioli (@bcuccioli).
|
|
- Moved the parse code from prototype math.expr.Parser to function math.parse,
|
|
simplified Parser a little bit.
|
|
- Strongly simplified the code of Scope and Workspace.
|
|
- Fixed function mod for negative numerators, and added error messages in case
|
|
of wrong input.
|
|
|
|
|
|
## 2013-05-18, version 0.8.2
|
|
|
|
- Extended the import function and some other minor improvements.
|
|
- Fixed a bug in merging one dimensional vectors into a matrix.
|
|
- Fixed a bug in function subtract, when subtracting a complex number from a
|
|
real number.
|
|
|
|
|
|
## 2013-05-10, version 0.8.1
|
|
|
|
- Fixed an npm warning when installing mathjs globally.
|
|
|
|
|
|
## 2013-05-10, version 0.8.0
|
|
|
|
- Implemented a command line interface. When math.js is installed globally via
|
|
npm, the application is available on your system as 'mathjs'.
|
|
- Implemented `end` keyword for index operator, and added support for implicit
|
|
start and end (expressions like `a(2,:)` and `b(2:end,3:end-1)` are supported
|
|
now).
|
|
- Function math.eval is more flexible now: it supports variables and multi-line
|
|
expressions.
|
|
- Removed the read-only option from Parser and Scope.
|
|
- Fixed non-working unequal operator != in the parser.
|
|
- Fixed a bug in resizing matrices when replacing a subset.
|
|
- Fixed a bug in updating a subset of a non-existing variable.
|
|
- Minor bug fixes.
|
|
|
|
|
|
## 2013-05-04, version 0.7.2
|
|
|
|
- Fixed method unequal, which was checking for equality instead of inequality.
|
|
Thanks @FJS2.
|
|
|
|
|
|
## 2013-04-27, version 0.7.1
|
|
|
|
- Improvements in the parser:
|
|
- Added support for chained arguments.
|
|
- Added support for chained variable assignments.
|
|
- Added a function remove(name) to remove a variable from the parsers scope.
|
|
- Renamed nodes for more consistency and to resolve naming conflicts.
|
|
- Improved stringification of an expression tree.
|
|
- Some simplifications in the code.
|
|
- Minor bug fixes.
|
|
- Fixed a bug in the parser, returning NaN instead of throwing an error for a
|
|
number with multiple decimal separators like `2.3.4`.
|
|
- Fixed a bug in Workspace.insertAfter.
|
|
- Fixed: math.js now works on IE 6-8 too.
|
|
|
|
|
|
## 2013-04-20, version 0.7.0
|
|
|
|
- Implemented method `math.eval`, which uses a readonly parser to evaluate
|
|
expressions.
|
|
- Implemented method `xgcd` (extended eucledian algorithm). Thanks Bart Kiers
|
|
(@bkiers).
|
|
- Improved math.format, which now rounds values to a maximum number of digits
|
|
instead of decimals (default is 5 digits, for example `math.format(math.pi)`
|
|
returns `3.1416`).
|
|
- Added examples.
|
|
- Changed methods square and cube to evaluate matrices element wise (consistent
|
|
with all other methods).
|
|
- Changed second parameter of method import to an object with options.
|
|
- Fixed method math.typeof on IE.
|
|
- Minor bug fixes and improvements.
|
|
|
|
|
|
## 2013-04-13, version 0.6.0
|
|
|
|
- Implemented chained operations via method math.select(). For example
|
|
`math.select(3).add(4).subtract(2).done()` will return `5`.
|
|
- Implemented methods gcd and lcm.
|
|
- Implemented method `Unit.in(unit)`, which creates a clone of the unit with a
|
|
fixed representation. For example `math.unit('5.08 cm').in('inch')` will
|
|
return a unit which string representation always is in inch, thus `2 inch`.
|
|
`Unit.in(unit)` is the same as method `math.in(x, unit)`.
|
|
- Implemented `Unit.toNumber(unit)`, which returns the value of the unit when
|
|
represented with given unit. For example
|
|
`math.unit('5.08 cm').toNumber('inch')` returns the number `2`, as the
|
|
representation of the unit in inches has 2 as value.
|
|
- Improved: method `math.in(x, unit)` now supports a string as second parameter,
|
|
for example `math.in(math.unit('5.08 cm'), 'inch')`.
|
|
- Split the end user documentation of the parser functions from the source
|
|
files.
|
|
- Removed function help and the built-in documentation from the core library.
|
|
- Fixed constant i being defined as -1i instead of 1i.
|
|
- Minor bug fixes.
|
|
|
|
|
|
## 2013-04-06, version 0.5.0
|
|
|
|
- Implemented data types Matrix and Range.
|
|
- Implemented matrix methods clone, concat, det, diag, eye, inv, ones, size,
|
|
squeeze, transpose, zeros.
|
|
- Implemented range operator `:`, and transpose operator `'` in parser.
|
|
- Changed: created construction methods for easy object creation for all data
|
|
types and for the parser. For example, a complex value is now created
|
|
with `math.complex(2, 3)` instead of `new math.Complex(2, 3)`, and a parser
|
|
is now created with `math.parser()` instead of `new math.parser.Parser()`.
|
|
- Changed: moved all data types under the namespace math.type, and moved the
|
|
Parser, Workspace, etc. under the namespace math.expr.
|
|
- Changed: changed operator precedence of the power operator:
|
|
- it is now right associative instead of left associative like most scripting
|
|
languages. So `2^3^4` is now calculated as `2^(3^4)`.
|
|
- it has now higher precedence than unary minus most languages, thus `-3^2` is
|
|
now calculated as `-(3^2)`.
|
|
- Changed: renamed the parsers method 'put' into 'set'.
|
|
- Fixed: method 'in' did not check for units to have the same base.
|
|
|
|
|
|
## 2013-03-16, version 0.4.0
|
|
|
|
- Implemented Array support for all methods.

|
|
- Improved parser for complex values math.Complex.parse(str);
|
|
- Improved method help: it now evaluates the examples.
|
|
- Fixed: a scoping issue with the Parser when defining functions.
|
|
- Fixed: method 'typeof' was not working well with minified and mangled code.
|
|
- Fixed: errors in determining the best prefix for a unit.
|
|
|
|
|
|
