function

scipy.special._basic:h1vp

source: /scipy/special/_basic.py :1139

Signature

def   h1vp ( v z n = 1 )

Summary

Compute derivatives of Hankel function H1v(z) with respect to z.

Parameters

v : array_like

Order of Hankel function

z : array_like

Argument at which to evaluate the derivative. Can be real or complex.

n : int, default 1

Order of derivative. For 0 returns the Hankel function hankel1 itself.

Returns

: scalar or ndarray

Values of the derivative of the Hankel function.

Notes

The derivative is computed using the relation DLFM 10.6.7 [2].

Examples

Compute the Hankel function of the first kind of order 0 and its first two derivatives at 1.
from scipy.special import h1vp
h1vp(0, 1, 0), h1vp(0, 1, 1), h1vp(0, 1, 2)
Compute the first derivative of the Hankel function of the first kind for several orders at 1 by providing an array for `v`.
h1vp([0, 1, 2], 1, 1)
Compute the first derivative of the Hankel function of the first kind of order 0 at several points by providing an array for `z`.
import numpy as np
points = np.array([0.5, 1.5, 3.])
h1vp(0, points, 1)
