{{alias}}( N, x, sx, y, sy, z, sz, clbk[, thisArg] )
    Performs element-wise subtraction of two strided arrays via a callback
    function and assigns each result to an element in an output strided array.

    The `N` and stride 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.

    The callback function is provided four arguments:

    - values: input array elements
    - idx: iteration index
    - indices: strided array indices (offset + idx*stride)
    - arrays: input and output arrays

    If the callback function does not return any value (or equivalently,
    explicitly returns `undefined`), the value is ignored.

    Parameters
    ----------
    N: integer
        Number of indexed elements.

    x: Array|TypedArray|Object
        Input array/collection. If provided an object, the object must be array-
        like (excluding strings and functions).

    sx: integer
        Index increment for `x`.

    y: Array|TypedArray|Object
        Input array/collection. If provided an object, the object must be array-
        like (excluding strings and functions).

    sy: integer
        Index increment for `y`.

    z: Array|TypedArray|Object
        Destination array/collection. If provided an object, the object must be
        array-like (excluding strings and functions).

    sz: integer
        Index increment for `z`.

    clbk: Function
        Callback function.

    thisArg: any (optional)
        Callback execution context.

    Returns
    -------
    z: Array|TypedArray|Object
        Destination array/collection.

    Examples
    --------
    // Standard usage:
    > var x = [ 11.0, 12.0, 13.0, 14.0 ];
    > var y = [ 8.0, 7.0, 6.0, 5.0 ];
    > var z = [ 0.0, 0.0, 0.0, 0.0 ];
    > function clbk( values ) { return values; };
    > {{alias}}( x.length, x, 1, y, 1, z, 1, clbk )
    [ 3.0, 5.0, 7.0, 9.0 ]

    // Using `N` and stride parameters:
    > z = [ 0.0, 0.0, 0.0, 0.0 ];
    > {{alias}}( 2, x, 2, y, -1, z, 1, clbk )
    [ 4.0, 5.0, 0.0, 0.0 ]

    // Using view offsets:
    > var x0 = new {{alias:@stdlib/array/float64}}( [ 11.0, 12.0, 13.0, 14.0 ] );
    > var y0 = new {{alias:@stdlib/array/float64}}( [ 8.0, 7.0, 6.0, 5.0 ] );
    > var z0 = new {{alias:@stdlib/array/float64}}( [ 0.0, 0.0, 0.0, 0.0 ] );
    > var x1 = new {{alias:@stdlib/array/float64}}( x0.buffer, x0.BYTES_PER_ELEMENT*1 );
    > var y1 = new {{alias:@stdlib/array/float64}}( y0.buffer, y0.BYTES_PER_ELEMENT*2 );
    > var z1 = new {{alias:@stdlib/array/float64}}( z0.buffer, z0.BYTES_PER_ELEMENT*2 );
    > {{alias}}( 2, x1, -2, y1, 1, z1, 1, clbk )
    <Float64Array>[ 8.0, 7.0 ]
    > z0
    <Float64Array>[ 0.0, 0.0, 8.0, 7.0 ]


{{alias}}.ndarray( N, x, sx, ox, y, sy, oy, z, sz, oz, clbk[, thisArg] )
    Performs element-wise subtraction of two strided arrays via a callback
    function and assigns each result to an element in an output strided array
    using alternative indexing semantics.

    While typed array views mandate a view offset based on the underlying
    buffer, the offset parameters support indexing semantics based on starting
    indices.

    Parameters
    ----------
    N: integer
        Number of indexed elements.

    x: Array|TypedArray|Object
        Input array/collection. If provided an object, the object must be array-
        like (excluding strings and functions).

    sx: integer
        Index increment for `x`.

    ox: integer
        Starting index for `x`.

    y: Array|TypedArray|Object
        Input array/collection. If provided an object, the object must be array-
        like (excluding strings and functions).

    sy: integer
        Index increment for `y`.

    oy: integer
        Starting index for `y`.

    z: Array|TypedArray|Object
        Destination array/collection. If provided an object, the object must be
        array-like (excluding strings and functions).

    sz: integer
        Index increment for `z`.

    oz: integer
        Starting index for `z`.

    clbk: Function
        Callback function.

    thisArg: any (optional)
        Callback execution context.

    Returns
    -------
    z: Array|TypedArray|Object
        Destination array/collection.

    Examples
    --------
    // Standard usage:
    > var x = [ 11.0, 12.0, 13.0, 14.0 ];
    > var y = [ 8.0, 7.0, 6.0, 5.0 ];
    > var z = [ 0.0, 0.0, 0.0, 0.0 ];

    [ 3.0, 5.0, 7.0, 9.0 ]

    // Advanced indexing:
    > x = [ 11.0, 12.0, 13.0, 14.0 ];
    > y = [ 8.0, 7.0, 6.0, 5.0 ];
    > z = [ 0.0, 0.0, 0.0, 0.0 ];
    > var oy = y.length - 1;
