scipy.special.sph_inkn(*args, **kwds)[source]

sph_inkn is deprecated! scipy.special.sph_inkn is deprecated in scipy 0.18.0. Use scipy.special.spherical_in and scipy.special.spherical_kn instead. Note that the new function has a different signature.

Compute spherical Bessel functions in(z), kn(z), and derivatives.

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

n : int

Maximum order of in and kn to compute

z : complex

Argument at which to evaluate

Returns:

in : ndarray

Value of i0(z), ..., in(z)

inp : ndarray

First derivative i0’(z), ..., in’(z)

kn : ndarray

Value of k0(z), ..., kn(z)

knp : ndarray

First derivative k0’(z), ..., kn’(z)
