Assignments

The problems below are from the textbook. Please write the solutions on separate pages (i.e., do not hand in a note-book), and STAPLE them.
The homeworks must be handed in during the Wed. class (unless specified otherwise).

LATE homeworks will receive a 20% penalty. I should receive them during the class following the one when the HW was due.

Some of the problems have the answer or a hint in the textbook. If you have to hand in such a problem, you are welcome to use the hint but have to still write a complete solution.
For problems that require Matlab, you can either hand in the printed Matlab computations, or a hand written copy of them.

ETC.
