Compile and run your routines with the main program ``getEdebug.c'' in Appendix C. This program accepts as input the number of integration intervals N and the number of states you want, and then returns all of the energies. At N=1000 intervals, you should be able to recover the first five states to within 5 decimal places. You should also be able to verify the scaling of your error in going from N=1000 to N=10000.
