{{alias}}( arrays, fcn )
|
||
|
|
Applies a unary callback to elements in an input ndarray and assigns results
|
||
|
|
to elements in an output ndarray.
|
||
|
|
|
||
|
|
Each provided "ndarray" should be an `object` with the following properties:
|
||
|
|
|
||
|
|
- dtype: data type.
|
||
|
|
- data: data buffer.
|
||
|
|
- shape: dimensions.
|
||
|
|
- strides: stride lengths.
|
||
|
|
- offset: index offset.
|
||
|
|
- order: specifies whether an ndarray is row-major (C-style) or column-major
|
||
|
|
(Fortran-style).
|
||
|
|
|
||
|
|
Parameters
|
||
|
|
----------
|
||
|
|
arrays: ArrayLikeObject<ndarray>
|
||
|
|
Array-like object containing one input ndarray and one output ndarray.
|
||
|
|
|
||
|
|
fcn: Function
|
||
|
|
Unary callback.
|

|
|
> var dtype = 'float64';
|

|
|
> var shape = [ 2, 2 ];
