/**
|
||
|
|
* Parse and compile an expression.
|
||
|
|
* Returns a an object with a function `evaluate([scope])` to evaluate the
|
||
|
|
* compiled expression.
|
||
|
|
*
|
||
|
|
* Syntax:
|
||
|
|
*
|
||
|
|
* math.compile(expr) // returns one node
|
||
|
|
* math.compile([expr1, expr2, expr3, ...]) // returns an array with nodes
|
||
|
|
*
|
||
|
|
* Examples:
|
||
|
|
*
|
||
|
|
* const code1 = math.compile('sqrt(3^2 + 4^2)')
|
||
|
|
* code1.evaluate() // 5
|
||
|
|
*
|
||
|
|
* let scope = {a: 3, b: 4}
|
||
|
|
* const code2 = math.compile('a * b') // 12
|
||
|
|
* code2.evaluate(scope) // 12
|
||
|
|
* scope.a = 5
|
||
|
|
* code2.evaluate(scope) // 20
|
||
|
|
*
|
||
|
|
* const nodes = math.compile(['a = 3', 'b = 4', 'a * b'])
|
||
|
|
* nodes[2].evaluate() // 12
|
||
|

|
||
|
|
* The expression to be compiled
|
||
|
|
* @return {{evaluate: Function} | Array.<{evaluate: Function}>} code
|
||
|
|
* An object with the compiled expression
