Special functions implementation ported from C++ libsparseir
This module provides high-precision implementations of special functions used in the SparseIR library, particularly spherical Bessel functions and related mathematical functions.
Functions§
- cyl_
bessel_ j - Cylindrical Bessel function of the first kind, J_nu(x)
- gamma_
func - Gamma function Γ(x) for real
x - spherical_
bessel_ j - Main function to calculate spherical Bessel function of the first kind
