Computation of Bessel and Neumann Functions.

Abstract

This memorandum describes the method by which a program was developed for evaluating Bessel and Neumann functions of integral order with real positive arguments. This method was developed specifically for use on small scale computers for which high computing speed can be obtained if excessive precision is avoided. The program allows the functions to be computed to five significant digits using six digits in the computation. The work described in this memorandum was carried out to allow computation of numerical values for solutions to the wave equation in cylindrical coordinates.
