scipy.special.ivp(v, z, n=1)[source]

Compute nth derivative of modified Bessel function Iv(z) 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, default 1

Order of derivative

Notes

The derivative is computed using the relation DLFM 10.29.5 [R508].
