(x, y, a=1.0)
Quick level-1 call to BLAS y = a*x+y.

    Parameters
    ----------
    x : array_like
        nx1 real or complex vector
    y : array_like
        nx1 real or complex vector
    a : float
        real or complex scalar

    Returns
    -------
    y : array_like
        Input variable y is rewritten

    Notes
    -----
    The call to get_blas_funcs automatically determines the prefix for the blas
    call.
Quick level-1 call to BLAS y = a*x+y.
Quick level - 1 call to BLAS y = a * x + y .
