{{alias}}( x )
    Returns a null-filled ndarray having the same shape and data type as a
    provided input ndarray.

    Along with data type, shape, and order, the function infers the "class" of
    the returned ndarray from the provided ndarray. For example, if provided a
    "base" ndarray, the function returns a base ndarray. If provided a non-base
    ndarray, the function returns a non-base ndarray.

    Parameters
    ----------
    x: ndarray
        Input array.

    Returns
    -------
    out: ndarray
        Output array.

    Examples
    --------
    > var opts = { 'dtype': 'generic' };
    > var x = {{alias:@stdlib/ndarray/empty}}( [ 2, 2 ], opts )
    <ndarray>
    > var y = {{alias}}( x )
    <ndarray>[ [ null, null ], [ null, null ] ]
