## Description

Title of program: MRVAC Catalogue Id: ACCV_v1_0 Nature of problem A wide variety of scattering problems can be reduced to solving sets of coupled differential equations wherein the coupling can be represented as a matrix series in r^-n at large values of r. The program is designed to produce solutions of the equations at an input value r = Ro, and to calculate a K-matrix to a specified accuracy from an input R-matrix at r = Ro.
