def METHOD_NAME(zeta):
    r"""
    The :term:`lite-function` version of
    `~plasmapy.dispersion.dispersionfunction.plasma_dispersion_func_deriv`.
    Performs the same calculation as
    `~plasmapy.dispersion.dispersionfunction.plasma_dispersion_func_deriv`,
    but is intended for computational use and, thus, has all data
    conditioning safeguards removed.
    Parameters
    ----------
    zeta : |array_like| of real or complex values
        Argument of the plasma dispersion function. ``zeta`` is
        dimensionless.
    Returns
    -------
    Zprime : |array_like| of complex values
        First derivative of plasma dispersion function.
