Hi
Just so we're all on the same page, there will be an exam on this Friday, Oct 12 during our 11:15 to 12:05 lecture. I'll give you around 55 minutes or a little more, by trying to begin the exam early and ending a little late, but the exam will be designed for 50 minutes. I don't have a practice exam.
Topics that are fair game for the exam include: Conditioning (both functions and matrices), stability, norms, operation counts, LU factorization, Gaussian elimination, special matrices, linear least squares, normal equations, orthogonality. As stated in the syllabus, these are topics up to and including section 3.2.
You will be allowed one 8.5x11 inch paper (both sides) that is a cheat sheet for the exam. Write down definitions, properties, whatever you want on that sheet.
You may also use Matlab, though the test will not be designed to significantly test you on Matlab syntax, for example. You may be asked: what a given bit of matlab is computing and whether it is a desired quantity; operation counts in Matlab (simpler than the qrfact.m problem from the last homework); or it may be advantageous to be able to do a command or two in matlab (nothing like writing a function or script).
You are not allowed: calculators, any other software besides matlab, cell phones, or any other electronic device (including ipods). I'll supply plain paper and the exam.
Advice for preparing: (1) Be able to solve the homework problems. If you didn't get them the first time, go back and be able to do them. (2) Make sure you remember your linear algebra or work extra problems in it if you don't feel confident about it. (3) Work the beginning Matlab exercises if you haven't already. (4) Don't wait until the last minute to start studying. Start tonight, and stop by and ask me questions if things seem murky. (5) Check out other numerical analysis books if reading something different may be helpful.
Best wishes,
RJB
