treams.special.spherical_yn_d

treams.special.spherical_yn_d(n, z)

Derivative of the spherical Bessel function of the second kind.

This is simply a wrapper for scipy.special.spherical_yn(n, z, True), see scipy.special.spherical_jn(). It’s here to have a consistent way of calling the derivative of a (spherical) Bessel or Hankel function.

Parameters:

  • n (int, array_like) – Order

  • z (float or complex, array_like) – Argument

Returns:

float or complex
