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
