{{alias}}( arrays, shape, fcn, clbk[, thisArg] )
    Applies a unary function to each element retrieved from a two-dimensional
    nested input array according to a callback function and assigns results to
    elements in a two-dimensional nested output array.

    The callback function is provided the following arguments:

    - value: array element.
    - indices: current array element indices.
    - arrays: input and output arrays.

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

    Parameters
    ----------
    arrays: ArrayLikeObject
        Array-like object containing one input nested array and one output
        nested array.

    shape: Array<integer>
        Array shape.

    fcn: Function
        Unary function to apply to callback return values.

    clbk: Function
        Callback function.

    thisArg: any (optional)
        Callback execution context.

    Examples
    --------
    > var x = [ [ -1.0, -2.0 ], [ -3.0, -4.0 ] ];
    > var y = [ [ 0.0, 0.0 ], [ 0.0, 0.0 ] ];
    > var shape = [ 2, 2 ];
    > function clbk( v ) { return v * 2.0; };
    > {{alias}}( [ x, y ], shape, {{alias:@stdlib/math/base/special/abs}}, clbk );
    > y
    [ [ 2.0, 4.0 ], [ 6.0, 8.0 ] ]
