scipy.special.sph_yn(n, z)[source]

Compute spherical Bessel function yn(z) and derivative.

This function computes the value and first derivative of yn(z) for all orders up to and including n.

Parameters:

n : int

Maximum order of yn to compute

z : complex

Argument at which to evaluate

Returns:

yn : ndarray

Value of y0(z), ..., yn(z)

ynp : ndarray

First derivative y0’(z), ..., yn’(z)
