This is a website to show how various numerical processes work, and how to use them to solve problems. There will be a pdf document which shows the details on how it works, with a fully worked out example. If the reader chooses to write their own program, they can use this example to help debug their program. Also, there will be a basic introductory program in Fortran or C to be used as a guide for solving them. Hopefully, the reader will use this information to write more sophisticated software to be used to solve ever more complex problems.
