Homework 3 is due October 21. The files
p1test, p1testgen, and p1todense should be used to test your
implementation of problem 1; use p2test and
p4test to test problems 2 and 4. You don't
need to write any code for problem 2, but should you be interested,
here is the source for constrained_ls and a test driver p3test.
The midterm exam is due in class on
Monday, October 26.
