- 10/25/09: Some notes about next week:
- The exam on Wednesday covers the material in NLA through lecture 11 (not
including Lecture 9 or Givens rotations from the homework)
- The exam is open book (only the NLA book). No calculators.
- We will not have class Monday. Instead, please read Lecture 20 in NLA on
Gaussian elimination.
- "Class" on Friday is to attend at least one talk in the
Red Raider
Minisymposium.
- I will be checking email periodically while on travel, so feel free to
email.
- 10/23/09: Review session TODAY at 5:00 in our
usual classroom. Come with questions.
- 10/23/09: I have posted partial solutions to HW5 below. The rest
should be up soon.
Note that on HW6 I also am having you skip 12.2 (d).
Don't forget the Ackleh problem in HW6.
- 10/20/09: Update to HW6.
I have decided that this
assignment is a little long (especially with an exam coming up). So I
am cutting a couple of things.
- Problem 14.1: do a, b, f, and g
- Problem 15.1: do a, b, c, and d
- (12.2 and 14.2 are unchanged.)
The parts I cut are still worth thinking about, but they are not
required for this assignment.
- 10/14/09: HW6 is posted below. Due Friday 10/23/09.
Our in-class midterm is scheduled for
Wednesday, 10/28/09. It will cover
material through NLA Lecture 11.
- 10/7/09: This week's office hours: Since HW5
(see below -- due 10/9/09) contains your
first graded MATLAB assignment, I will hold my office hours this week
in the Math 113 computer lab. I highly recommend that you start the
assignment early, especially if you are new to MATLAB.
For the coding assignment (8.2 or 10.2), test your code by comparing
the results of your code with MATLAB's build-in qr on a small random
rectangular matrix of size 8 x 5. Turn in a print out of your
(clearly commented and formatted) code (m-file) and the results of your test.
- 9/25/09: HW4 is posted. Due Friday
10/2/09.
Here are a couple of recommended problems to start getting comfortable with
MATLAB. You do not need to turn these in, but I highly recommend doing
them: NLA 8.2 and 9.3.
I would also recommend working through the
three experiments in Lecture 9 with MATLAB running so you can try
things out.
- 9/16/09:Solutions to HW1 are posted below.
- 9/12/09:HW 3 is posted below.
Due Friday, 9/18/09, by 4:00 p.m.
- 9/11/09:
I apparently posted the wrong version of the syllabus a
while back. I have replaced the syllabus above. Note
that there is no course project. Grades are based on homework, an
in-class midterm, and the final exam, as I had said in class.
Note that some browsers will keep giving you the old copy because
downloads are stored in cache. I had to clear my cache by hand to see
the new file. (In firefox, you can go to Edit -> Preferences -> Advanced
-> Network. There is an option next to cache size to Clear Now. Other
browsers should have a similar option.) If you are getting the correct
version of the syllabus, it should show seven late days and no course
project.
- 9/4/09: HW 2 is posted below.
Due Friday, 9/11/09, by 4:00 p.m.
- 8/28/09: HW 1 was assigned today (see below). Due
Friday, 9/4/09, by 4:00 p.m.
- Note the late HW policy below.
- Remember that it is OK to work together on homework problems. But your
write up (including any code) that you turn in must be your own.
- If you do not yet have a copy of the Trefethen & Bau book, but want to get
started on the homework, the first five chapters (including exercises) are
available for download on the
author's
web page.
- 8/28/09: 1st day of class. Check this space for class announcements.
