# A program to calculate green's functions

## Description

Title of program: GRN1 Catalogue Id: ACWN_v1_0 Nature of problem Regular and irregular solutions to a one-dimensional differential equation are obtained for the cases where the potential includes a Coulomb term and/or a centrifugal barrier, and for positive or negative energies. These Green's function solutions are necessary, for example, in the solution of a scattering problem by non-iterative integral equation method.
