Problem Sets and Data Resources for 12.747

The general format of these assignments will be text that you can obtain by clicking on the links below. Each assignment will generally involve downloading data files from the web site (use right-click or shift-click), loading the data into MATLAB (use load command), operating on the data, creating an "m-file" to run the analysis, and emailing the m-file to the Instructor.

The answers can be obtained by shift-clicking the links to the m-files listed. Run them as you would your own m-files to see the answers, read them to learn how it was done.
