**Assignments**

l The problems and due time for every assignment will be posted on WebAssign one week before it is due. The current
information on WebAssign is not correct, and will be
updated after the relevant material is covered.

l In general, WebAssign problems will be
due one week after the relevant material is covered in class, at 11:59 pm.
Hand-graded problems (the * and Matlab problems in
the assignment sheet) will be due on the Friday of the following week, at the
beginning of class.

l You can login to WebAssign at https://www.webassign.net/purdue/login.html.
You will have a two week grace period before you have to enter a Webassign access code or buy access online.

l For the hand-graded homework, please print your Matlab session(s) and write notes/answers on it when
appropriate. It is also required to staple your printed Matlab
session(s) with other written (*) problems. To print your Matlab
session, you may:

1.
Right-click on the session
(anywhere in the command window), and choose Print....

2.
Use the combination Ctrl+P when the session is selected.

3.
In the drop-down list on the
top right of the session, choose Print....

l For your printed Matlab homework, you
should:

1.
Have the code and the results
from matlab, as well as necessary comments.

2.
Answer the problems fully,
don't miss any parts.

3.
Do the problems in order as
best as you can. Write where to find the missing problems if you couldn't do
them in order.

4.
Number your answers.

l In hand-graded homework, you should always justify your answer. In
particular, "show that ..." does not mean "to find an example
that ...", but rather "explain that ... is true", which really
is just another way of saying "prove that..." In this course, we will
take examples together with an explanation why this examples shows the
statement is true in full generality. An example by itself is not enough. You
can, of course, choose to do a formal proof in place of the above, but that is
not required.

l Before you hand in your homework, make sure you:

2.
Wrote your name clearly.

l Technical problems are not sufficient ground for homework
extension. It is your responsibility to make sure your computer, internet, Matlab, browsers, etc. are in working condition to complete
your homework on time. Browser incompatibility is the source of a lot of
problems when doing WebAssign homework. You are
strongly encouraged to use "well known" browsers (Chroe,
Firefox, Explorer, Safari, etc.) to do your homework.

**Some
advises on how to do well in this class**

l Take notes during the classes, and review them after classes.

l
Raise your hand and ask
questions immediately if something is unclear for you during the class.

l
Read the textbook and do the
homework as well as practice another version on WebAssign
if you are struggling with a problem.

l
Practice past exams.

l
Come to office hours or e-mail
me if you have any questions.

l
Try other online resources,
for example Khan Academy.

**FAQ**

l Q: Where can I see the details for hand-graded homework on WebAssign?

A: Click on the My Assignment tab at the top of the page (not the other one
below it, which is not a link.)

l Q: What should I do if my Matlab shows
"Undefined function ..." for some functions (e.g. project, matdat, invert, rowop, gschmidt, etc.)?

A: You should download the routines on the course
webpage, unzip it, and save it to your current Matlab
routine folder (the path shown in Matlab.)

l Q: My Matlab book is missing Sec 10.3.

A: You can download the missing pages on the course
webpage.
