treams.special.spherical_hankel1_d

treams.special.spherical_hankel1_d(n, z) = <ufunc 'spherical_hankel1_d'>

Derivative of the spherical Hankel function of the first kind.

Computed by

\[{h_n^{(1)}}'(z) = \frac{n h_{n - 1}^{(1)}(z) - (n + 1) h_{n + 1}^{(1)}(z)}{2n + 1}\]
Parameters:
  • n (integer, array_like) – Order

  • z (complex, array_like) – Argument

Returns:

complex
