Note that the Zhang and Jin book alsoĬontains code for Bessel functions of complex arguments. Obtained in this code were found to match the values in these 2 sources. Some values for Bessel functions of complex arguments can be found in Computation of Specialįunctions by Shanjie Zhang and Jianming Jin, copyright 1966 by John Wiley & Sons, Inc. In Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables Edited by Milton Abramowitz and 2.) Bessel function tables for real arguments as given
Forĭoublechecking this code 2 possibilities exist: 1.) The 6 self tests included in the package - zqcbh, zqcbi, zqcbj, Theĭecision to port this code was prompted by the fact that the MATLAB links to this Amos FORTRAN package. The original FORTRAN code was downloaded from. This is an installation of his Algorithm 644,Ĭollected Algorithms form ACM. Amos at the Sandia National Laboratories. This work is the port of FORTRANĬode written by Donald E. This module computes Bessel functions of complex arguments and a nonnegative order.
