scipy.special.sph_in(n, z)[source]¶

Compute spherical Bessel function in(z) and derivative.

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

Parameters:	n : int Maximum order of in 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)
