{{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 ]
