Organisation

For the course "Linear algebra and image processing" (Lineaire Algebra en Beeldverwerking) there are lectures ("Hoorcolleges") and exercise classes ("Werkcolleges"). In each werkcollege the last 20 minutes will be a multiple-choice test on the material from the course up to that point. This will count towards your final grade.

The first lecture is on Thursday 5th February at 11:15 in room B2 (Snellius).

The first test is on Thursday 12th February at 10:00 in room B2 (Snellius).

Note that the day of the lecture is changed in weeks 9/10 (see the timetable for details)

See timetable here.

Required Literature

We will follow closely parts of the book "Linear algebra and its applications" by David Lay. Every student will need a copy of the book; for example, weekly exercises will be set from the book, and the tests will contain similar questions.

Where and when?

Timetable.

Assessment

Weekly tests

As noted above, there will be a short multiple-choice test held every week during the Werkcollege. You can see a sample of the test here. Bring a soft pencil and an eraser to every test.

Examinations

There is one exam for the course, after the end of the course (on 28th May). The exam will last 3 hours. It will cover material from the whole course, including that already covered in the weekly tests.

Calculating the final grade

Firstly, the weekly tests. There will be 13 tests in total. Your best 10 marks will count. Write W for the average of your best 10 tests. Write E for your grade on the final exam.

The total examination grade is is then the weighted average:

Final grade = 0.25*W + 0.75 * E.

Homework and classes

Each week, some problems from the book will be suggested. These will not be graded, and will not count towards the final grade. However, you are extremely strongly recommended to attempt all the problems - the problems in the short tests and the final exam will be similar, and past experience suggests that ability to do he homework problems is a very strong predictor of success in the course. The problems will be discussed during the classes, and you will have the opportunity to obtain help on problems you found difficult.

Office hours

Office hours of the lecturer will be from 09:30 -12:00 on Mondays (or by appointment) in room 233 in Snellius.

Content and detailed timetable

The first column is the date of the monday of the week (note the lectures and the exercise classes are on thursdays). The second column refers to chapters of the course book "Linear algebra and its applications" [Lay]. The final column contains the reccomended exercises from [loc.cit]; `H1.1:4,8' means exercises 4 and 8 from the end of chapter 1.1 of the book.
