scipy.special.sph_yn

scipy.special.sph_yn(*args, **kwds)

sph_yn is deprecated! scipy.special.sph_yn is deprecated in scipy 0.18.0. Use scipy.special.spherical_yn instead. Note that the new function has a different signature.

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)
