- Due 4:30 PM Monday, January 31st 2000
Of the handwritten exercises, only the ones shown in boldface are to
be handed-in. All others are strongly recommended but not to be handed-in.
Maple exercises are to be done on the computer, printed-up, and stapled to
the end of your handwritten work. Solutions to all these problems will be
posted after the assignment is due.

(See the posted Using Elementary Matrices in Maple and
Finding the Inverse of a Matrix in Maple.)
- Make a random 3 by 3 matrix, with the random number generator seeded to
your student ID number (all 9 digits), using the following commands:
>
with(linalg):
>
readlib(randomize);
>
randomize(981234567);
Note: Use your own student ID number here, not "981234567"!
>
A:=matrix(3,3,rand(-5..5));
- Find the inverse of "A" using Maple's "inverse" command.
- Find the inverse of "A" in Maple using the Gauss-Jordan method.
- Now do #3 showing all the Elementary Row Operations in Maple.
- Use #4 to express "A" as a product of Elementary Matrices in Maple.
