{{alias}}( arrays )
    Multiplies a one-dimensional single-precision floating-point ndarray `x`
    by a constant `alpha` and adds the result to a one-dimensional single-
    precision floating-point ndarray `y`.

    If provided an empty input ndarray, the function returns the output ndarray
    unchanged.

    Parameters
    ----------
    arrays: ArrayLikeObject<ndarray>
        Array-like object containing the following ndarrays:

        - a one-dimensional input ndarray.
        - a one-dimensional output ndarray.
        - a zero-dimensional ndarray containing a scalar constant `alpha`.

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

    Examples
    --------
    > var x = new {{alias:@stdlib/ndarray/vector/float32}}( [ 4.0, 2.0, -3.0, 5.0, -1.0 ] );
    > var y = new {{alias:@stdlib/ndarray/vector/float32}}( [ 2.0, 6.0, -1.0, -4.0, 8.0 ] );
    > var alpha = {{alias:@stdlib/ndarray/from-scalar}}( 5.0, { 'dtype': 'float32' });

    > {{alias}}( [ x, y, alpha ] );
    > y
    <ndarray>[ 22.0, 16.0, -16.0, 21.0, 3.0 ]
