Problem Set 4 and 5 is uploaded on the Course Materials page. The deadline is December 3, 2011. Feel free to take help from the solutions code uploaded under Week 5 at Fall 2010 page. All questions must be solved on MATLAB in the form of code/program. No paper-and-pencil result would be accepted/graded. You must zip your files into one folder and name it as your_name_pset_3. Any questions, comments, corrections and exposition on the problem set are most welcome and can be asked by commenting on this (blog) post. Your submissions must be your own work as plagiarism would result in severe penalty. Mathematical expressions can be typed in the comment-box by using lateX typesetting scheme in wordpress. Best of luck for the assignment and feel free to discuss any related questions with me.
