Course topics

We will cover chapters 1 through 6 in the textbook and singular value decomposition and the pseudoinverse (appendix A). If time permits we will also include either chapter 7 or 8 and Jordan form (appendix B). Here is a detailed list of the course contents.

You can review the catalogue description for math 4305.


There will be two in-class exams, 30% each, and a comprehensive final, 40%. Letter grades will be determined according to the following standard scale:

 90% ≤ A ≤ 100%
80% ≤ B < 90%
70% ≤ C < 80%
60% ≤ D < 70%
            F < 60%.

If a curve is needed, it will be calculated after the final exam. Exam regrades will be accepted up to 1 week following distribution of graded exams to the class. Only under special circumstances will a student be allowed to make up a test; if applicable, a doctor's note or a letter from the dean of students will be required.

Homework: about three times a week list of problems from your textbook will be posted for you to practice. Homework may be be collected and corrected but it will not count toward your final grade; however, you are strongly encouraged to work on as many of the assigned problems as you can.

Class notes: even though I would prefer you read the textbook, as I prepare for class I tend to write detailed lecture notes or just scribblings (time, you know?). I'll try to post them regularly if you think they could help you understand better the material!

1st week.
Appendix A: (4x4 example of LU factorization with permutation)
2ndweek: more notes on ch 1 (there's no page 20 yet). notes on ch 2 (page 28 is in the next set).
3rd week. In preparation, a more definitive version is still to appear.

Grade distributions: will be posted in due course.

Important announcements: additional information will be posted as needed. Please check the web page regularly.

Sample test 1 (alpha) (Solutions to alpha)      Sample test 1 (beta) (Solutions to beta)

• For your benefit, we tried to write detailed answers for the sample tests. You may want to write answers whose level of explanation would also take into account the 70-min time constraint.

• You may bring to the test one sheet of notes, letter size, both sides, written with your own hand writting. The use of calculators, classnotes and texbooks will not be allowed.

• Test 1 will cover all sections indicated in the homework problem list. If a section is not mentioned in the hw list it won't be included in the test.
