{{alias}}( shape, idx[, options] )
|
||
|
|
Converts a linear index to an array of subscripts.
|
||
|
|
|
||
|
|
Parameters
|
||
|
|
----------
|
||
|
|
shape: ArrayLike
|
||
|
|
Array shape.
|
||
|
|
|
||
|
|
idx: integer
|
||
|
|
Linear index.
|
||
|
|
|
||
|
|
options: Object (optional)
|
||
|
|
Options.
|
||
|
|
|
||
|
|
options.order: string (optional)
|
||
|
|
Specifies whether an array is row-major (C-style) or column-major
|
||
|
|
(Fortran style). Default: 'row-major'.
|
||
|
|
|
||
|
|
options.mode: string (optional)
|
||
|
|
Specifies how to handle a linear index which exceeds array dimensions.
|
||
|
|
If equal to 'throw', the function throws an error when a linear index
|
||
|
|
exceeds array dimensions. If equal to 'wrap', the function wraps around
|
||
|
|
a linear index exceeding array dimensions using modulo arithmetic. If
|
||
|
|
equal to 'clamp', the function sets a linear index exceeding array
|
||
|
|
dimensions to either `0` (minimum linear index) or the maximum linear
|
||
|
|
index. Default: 'throw'.
|
||
|
|
|
||
|
|
Returns
|
||
|
|
-------
|
||
|
|
out: Array<integer>
|
||
|
|
Subscripts.
|
||
|
|
|
||
|
|
Examples
|
||
|
|
--------
|
||
|
|
> var d = [ 3, 3, 3 ];

> var s = {{alias}}( d, 17 )
|
||
|
|
[ 1, 2, 2 ]
|
||
|
|
|
||
|
|
|
||
|
|
{{alias}}.assign( shape, idx[, options], out )
|
||
|

provided output array.
