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

  Compute nth derivative of Bessel function Yv(z) with respect to z.

  Parameters: | v : float Order of Bessel function z : complex Argument at which to evaluate the derivative n : int, default 1 Order of derivative

  Notes

  The derivative is computed using the relation DLFM 10.6.7 [R546].
