scipy.special.kvp(v, z, n=1)

Compute nth derivative of real-order modified Bessel function Kv(z)

Kv(z) is the modified Bessel function of the second kind. Derivative is calculated with respect to z.

Parameters:

v : array_like of float

Order of Bessel function

z : array_like of complex

Argument at which to evaluate the derivative

n : int

Order of derivative. Default is first derivative.

Returns:

out : ndarray
