You are encouraged to work in groups, but must write an individual report for each problem set. Please specify in the report if you did the problem set together with someone else. The report must consist of any output generated by matlab, and a personal commentary on the results. This personal commentary is extremely important, as it is the only completely individual part of the work. You may be asked to send your commented matlab code by e-mail for verification, so make sure you keep it safely backed up, and please include your e-mail address in the report. Due dates are strict: for every day late you get -1 point (out of 10).
