# scipy.special.yvp

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

  Compute derivatives of Bessel functions of the second kind.

  Compute the nth derivative of the Bessel function Yv 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

  Returns
    scalar or ndarray

      nth derivative of the Bessel function.

  Notes

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