Welcome to my web site for problems, projects and software associated with this book. The web site is divided in to web pages in the same way as my book is divided into sections and chapters. In the page for each chapter there are copies of some suggested problems or projects which I think are suitable for incorporating into graduate programmes which have a project element. Also available are example programs which have been used to generate some of the figures in the book. The programs are provided as examples and I certainly do not claim to be a great programmer so beware my little idosyncrasies or bad habits left over from learning little dodges for Fortran in the late 1960's. The programs are variously written in fortran, C or matlab. All three programming languages have their uses but anyone starting out in numerical computation is well advised to become fluent in matlab because of its highly efficient algorithms and powerful graphics routines.
