{{alias}}( arrays, shape, strides, fcn )
Applies a unary callback to elements in a strided input array according to
elements in a strided mask array and assigns results to elements in a
strided output array.
The `shape` and `strides` parameters determine which elements in the strided
arrays are accessed at runtime.
Indexing is relative to the first index. To introduce an offset, use typed
array views.
Parameters
----------
arrays: ArrayLikeObject<ArrayLikeObject>
Array-like object containing one strided input array, a strided mask
array, and one strided output array.
shape: ArrayLikeObject<integer>
Array-like object containing a single element, the number of indexed
elements.
strides: ArrayLikeObject<integer>
Array-like object containing the stride lengths for the strided arrays.
fcn: Function
Unary callback.
Examples
--------
> var x = new {{alias:@stdlib/array/float64}}( [ -1.0, -2.0, -3.0, -4.0 ] );
> var m = new {{alias:@stdlib/array/uint8}}( [ 0, 0, 1, 0 ] );
> var y = new {{alias:@stdlib/array/float64}}( [ 0.0, 0.0, 0.0, 0.0 ] );
> var shape = [ x.length ];
> var strides = [ 1, 1, 1 ];
> {{alias}}( [ x, m, y ], shape, strides, {{alias:@stdlib/math/base/special/abs}} );
> y
<Float64Array>[ 1.0, 2.0, 0.0, 4.0 ]
{{alias}}.ndarray( arrays, shape, strides, offsets, fcn )
Applies a unary callback to elements in a strided input array according to
elements in a strided mask array, and assigns results to elements in a
strided output array using alternative indexing semantics.
While typed array views mandate a view offset based on the underlying
buffer, the `offsets` parameter supports indexing semantics based on
starting indices.
Parameters
----------
arrays: ArrayLikeObject<ArrayLikeObject>
Array-like object containing one strided input array, a strided mask
array, and one strided output array.
shape: ArrayLikeObject<integer>
Array-like object containing a single element, the number of indexed
elements.
strides: ArrayLikeObject<integer>
Array-like object containing the stride lengths for the strided arrays.
offsets: ArrayLikeObject<integer>
Array-like object containing the starting indices (i.e., index offsets)
for the strided arrays.
fcn: Function
Unary callback.
Examples
--------
> var x = new {{alias:@stdlib/array/float64}}( [ -1.0, -2.0, -3.0, -4.0 ] );
> var m = new {{alias:@stdlib/array/uint8}}( [ 0, 0, 1, 0 ] );
> var y = new {{alias:@stdlib/array/float64}}( [ 0.0, 0.0, 0.0, 0.0 ] );
> var shape = [ x.length ];
> var strides = [ 1, 1, 1 ];
> var offsets = [ 0, 0, 0 ];
> {{alias}}.ndarray( [ x, m, y ], shape, strides, offsets, {{alias:@stdlib/math/base/special/abs}} );
> y
<Float64Array>[ 1.0, 2.0, 0.0, 4.0 ]
