**Computer Help Resources**

Here is the directory with the Maple script files and the Maple printout from the first class.

Please bring a printed copy of the
`REF.mpl` Maple program to class on Thursday, Jan 18.

I've discovered a bug in `mysolve.mpl`: Line 39 should
read `for k from i+1 to m do` instead of
`for k from i+1 to n do`.

**First homework is due tomorrow at 1pm**.

I've discovered an inaccuracy in the help page for `ref`.
The procedure does not compute a reduced ref, just a ref.

There are new Maple functions in the
`Maple/REF` directory.
Please obtain a copy.

The file `REF/elem_mats.mpl`
contains functions to construct elementary matrices. Please use them
for understanding how they look. E.g., `E_I(10, 7, 9)`
is the matrix that exchanges row 7 and 9 on a 10 row matrix.
Note that the first argument is the dimension of the matrix.
I have also added a trace to `myinverse.mpl`. Set
`printlevel := 3` and all elementary operations performed
will be printed.

Problem 3 of Homework 3 is due February 13 (partitioned matrices were not covered yet).

The first midterm is graded. You can find a sorted list of all grades in the file sorted_grades in the exam directory.

Instructions for examination on Thursday.

My hand-written class notes are on reserve in the library. I will add on as I prepare new material.

A Maple example for computing the nullspace and a selected solution via CEF can be found in the directory Maple/REF (obtain the Maple script file from there).

For homework 6, some of the section numbers were wrong. Page and problem numbers were right. Now it should be correct.

Sorted grades for exam 2 (excluding 3 people taking make-up exams).

Homework 8 is assigned.

"Famous" quotes (about false impossibilities).

Financial aid practices of private universities (Wall Street Journal article).

Homework 9 is assigned. Click on Maple hints for how to produce the multiple point/function plot.

Message on a record-breaking factorization of a cryptokey.

The **student evaluation** of this course will take place at the beginning of
class, Tuesday, April 23. Please bring a **soft pencil** to class that day.

Homework 11 is assigned.

Maple function calls for solving the differential equations from class directly (answer to Heather Chudalski's Q).

NY Times article on a bug in our Netscape browser.

Mike's exam week office hours are Monday, Apr. 29, 2-6pm

Erich's extra office hours are on **Monday, Apr 29, 5pm-6pm.**

Topics **and practice problems** for final examination.
Copies of the remaining personal class notes are now on reserve in the library.

The **final exam** is scheduled for Tuesday, April 30, from 1-4pm.
