Description

Title of program: BESSCC Catalogue Id: ABBM_v1_0 Nature of problem The BESSCC subroutine calculates the modified Bessel functions Imu(z) and Kmu(z) (and derivatives) for complex argument z and a sequence of real orders mu,mu+1,...,mu+n-1 for integer N >/= 1. These functions arise in the solutions of potential problems in spherical and cylindrical coordinates. They can also be used to calculate ordinary Bessels Jmu(z), Ymu(z), spherical Bessels Jmu(z), Ymu(z), Kelvin and Airy functions.
