scipy.special.sph_jnyn

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

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

Compute spherical Bessel functions jn(z) and yn(z) and derivatives.

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

Parameters:

n : int

Maximum order of jn and yn to compute

z : complex

Argument at which to evaluate

Returns:

jn : ndarray

Value of j0(z), ..., jn(z)

jnp : ndarray

First derivative j0’(z), ..., jn’(z)

yn : ndarray

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

ynp : ndarray

First derivative y0’(z), ..., yn’(z)
