def ivp(v, z, n=1) 

Description

ivp.__doc__

Compute derivatives of modified Bessel functions of the first kind.

    Compute the nth derivative of the modified Bessel function `Iv`
    with respect to `z`.

    Parameters
    ----------
    v : array_like
        Order of Bessel function
    z : array_like
        Argument at which to evaluate the derivative; can be real or
        complex.
    n : int, default 1
        Order of derivative

    Returns
    -------
    scalar or ndarray
        nth derivative of the modified Bessel function.
