If you are an instructor and looking for solutions, please email me at david.barber@ucl.ac.uk. You will need to provide me with evidence of your academic appointment and that you're using the book on a course. You will need to send me an email from your official institution email account (not gmail/hotmail etc) and also a link to your personal webpage at your institution.

I'll then email you the password to the solutions which also contains the matlab solution files and Latex slides for presentations.
