# scipy.special.ivp

`scipy.special.``ivp`(v, z, n=1)

  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 [R451].
