A Fortran subroutine, COULFG, computes the regular and irregular Coulomb wave functions F and G, and their derivatives dF/dx and dG/dx. These functions depend on two parameters, eta and L in the notation of Abramowitz and Stegun, Handbook of Mathematical Functions, NBS Applied Mathematics Series 55. A single call to COULFG computes the functions for fixed positive x, fixed real eta, and a range of L-values in integer steps.
