Debugging

Run your ``ludcmpp480'' and ``lubksbp480'' routines with the main program in Appendix E. This test builds a 6$times$6 linear system, uses the LU routines to solve it, and then tests the result. You may use this main program as a model of how to use the LU routines to solve the linear system ${\bf G} \vec b = \vec u$ in 5.3.2.
