Professor Bender has prepared similar notes, also available in PDF and postscript formats.

Corrections from hardcopy handed out: you do not need to know kernel, image or homogeneous coordinates.

**Other resources: **

OASIS
has free tutoring, TuTh 2:00-3:50 Center 330, TuTh, 4:00-5:50, Center 356.

The

**Section meetings:
** Tuesday section meetings begin
January 14 (week two). They review upcoming homework problems, collect the
completed computer assignments, and (most weeks) give a quiz. Please
attend the Tuesday section in which you are officially enrolled. If you
want to change sections, please try to do so through the add/drop process.
In exceptional cases, you may attend another section.

Thursday section meetings begin January 9, but the first computer assignment begins the next week. They meet in the computer lab and you work on your computer assignment in section. You are encouraged, but not required to attend the Thursday section in which you are enrolled.

**Lecture topics. **
A list of the topics covered in the lectures
(usually updated a day or two **after** the lecture).

**Homework assignments. **

We do not yet know if these can be
graded; however, you must do them and hand them in.

Homeworks are to be handed in weekly
in the Wednesday lecture. You can discuss them in the Tuesday section
meetings.

**Matlab assignments. **
Weekly computer assignments, Thursday sessions, due

course Matlab page for changes in due dates!

**Quizzes. **
Quizzes held most weeks on Tuesday, on preannounced topics, and take approximately 15
minutes.

Quizzes will be held in the last 15
minutes of the Tuesday section meetings. (This could change to be held

The "Basic Skills" study guide has been updated for the
final.

**Grading. ** The final exam and the two midterm exams
will count the most, 35% for the final, and 20% for each of the two midterms.
The quizzes and lab assignments, and homeworks, and will each count for about 5
to 10% of the course grade. (Percentages are only approximate and are
subject to minor changes.)

Although the percentages for homework assignments, quizzes
and labs are low, they are a required part of the course. If you
completely omit doing the Matlab assignments, for instance, then your grade may
be reduced beyond the indicated percentage.

**Identification. ** We have a large
class, and it is time-consuming to keep track all the grades. Please label
all assignments and exams with (a) **your name, **(b) **your student ID
number,** and (c) the time of the section that you attend (so we can
return it to you). If you prefer to use a name different from that in the
official UCSD records, please put both versions of your name! Poorly
labeled assignments may receive reduced credit.

**Academic integrity.** Academic
integrity is very important, and if cheating is detected (particularly on exams)
it will treated seriously, possibly including referral to a dean.

For homework problems and computer lab work, it is permitted
to work with other students or in groups or to get help from a TA or instructor,
**but** you should write your solutions on your own. If someone shows
you an answer to a homework problem, you should wait at least 10 minutes and
then try to write up the answer on your own. This is to be sure you are
really learning the homework material! If someone helps you with a
computer lab, you should be sure that you **do all your own typing**, and
that you understand how to do it.
