scipy.special.sph_kn¶

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

Compute spherical Bessel function kn(z) and derivative.

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

Parameters: n : int Maximum order of kn to compute z : complex Argument at which to evaluate kn : ndarray Value of k0(z), ..., kn(z) knp : ndarray First derivative k0’(z), ..., kn’(z)
