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)
