{{alias}}( arrays )
    Concatenates a list of one-dimensional or two-dimensional ndarrays as rows.

    One-dimensional input ndarrays having length `N` are promoted to two-
    dimensional ndarrays having shape `[1, N]`.

    Each input ndarray must have the same number of columns.

    The data type of the output ndarray is determined by applying type
    promotion rules to the list of input ndarrays.

    If provided ndarrays having different memory layouts, the output ndarray
    has the default order.

    Parameters
    ----------
    arrays: ArrayLikeObject<ndarray>
        List of input ndarrays. Each input ndarray must be either one-
        dimensional or two-dimensional and must have the same number of
        columns.

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

    Examples
    --------
    > var x = {{alias:@stdlib/ndarray/array}}( [ 1.0, 2.0, 3.0 ] );
    > var y = {{alias:@stdlib/ndarray/array}}( [ [ 4.0, 5.0, 6.0 ], [ 7.0, 8.0, 9.0 ] ] );
    > var out = {{alias}}( [ x, y ] )
    <ndarray>[ [ 1.0, 2.0, 3.0 ], [ 4.0, 5.0, 6.0 ], [ 7.0, 8.0, 9.0 ] ]


{{alias}}.assign( arrays, out )
    Concatenates a list of one-dimensional or two-dimensional ndarrays as rows
    and assigns results to a provided output ndarray.

    One-dimensional input ndarrays having length `N` are promoted to two-
    dimensional ndarrays having shape `[1, N]`.

    Each input ndarray must have the same number of columns.

    Input ndarrays must promote to a data type which can be (mostly) safely
    cast to the data type of the output ndarray.

    Parameters
    ----------
    arrays: ArrayLikeObject<ndarray>
        List of input ndarrays. Each input ndarray must be either one-
        dimensional or two-dimensional and must have the same number of
        columns.

    out: ndarray
        Output ndarray. Must be a two-dimensional ndarray and must have a data
        type to which the input ndarrays can be (mostly) safely cast.

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

    Examples
    --------
    > var x = {{alias:@stdlib/ndarray/array}}( [ 1.0, 2.0, 3.0 ] );
    > var y = {{alias:@stdlib/ndarray/array}}( [ [ 4.0, 5.0, 6.0 ], [ 7.0, 8.0, 9.0 ] ] );
    > var z = {{alias:@stdlib/ndarray/zeros}}( [ 3, 3 ] );
    > var out = {{alias}}.assign( [ x, y ], z )
    <ndarray>[ [ 1.0, 2.0, 3.0 ], [ 4.0, 5.0, 6.0 ], [ 7.0, 8.0, 9.0 ] ]
    > var bool = ( out === z )
    true
