RE: Still Struggling with MATLAB?
Dear math 293: 10/18/96
The mid-course evaluations and first prelim make it clear that SOME people
are still struggling with MATLAB basics.
If you answer yes to these questions we are talking about you.
Did you not get MATLAB in CS100 (because you didn't take the course,
you blew-off MATLAB, or they didn't teach enough)?
Did you never follow the recomendation in the first handout
"... you may want to spend 3-5 hours slowly
going through the tutorials in [Pratap's MATLAB] book."
and not slowly do the tutorials AND exercises?
Did you never do the first problem on the first homework assignment:
"1. Make sure you can do all the tutorials and all problems in
the tutorials in Pratap's MATLAB book."?
Do you find yourself frustrated when doing problems in MATLAB without
essentially copying lecture samples, WWW samples, or other people's
work?
Do you feel like you don't have time to go back and learn this stuff
because you're too busy writing up your homework?
Well, here it is.
A PRESIDENTIAL PARDEN. Thats right, Mr Dole take note, we are offering
some of our top people an official parden.
YOU ARE HEREBY EXCUSED from handing in any homework assignment of your
choice, in math 293 only, any time between now and the end of the semester.
You will get full credit for any one assignment by truthfully writing
(or scotch taping and signing) the first paragraph below and as much else
as is true.
"I spent 6 hours or more THIS week learning MATLAB.
I did the 5 tutorials in the Pratap MATLAB book on pages 15-37;
I copied the tutorial examples and did enough of the exercises so that
I felt I could do them all (without looking up the solutions).
I read pages 147-152 about MATLAB errors and have been able to
find errors in my MATLAB commands by understanding these error messages.
I read pages 39-54(top), 55(bottom)-58, 73-87, and PRACTICED those
commands and skills that seem appropriate to me in terms of this course
including, for example, A*B, A.*B, inv(A), A(:,3), [V D]=eig(A), A'.
I have read, executed, and modified the Course MATLAB samples
on the WWW page (not DFIELD and PPLANE but the others).
I have a sense of how having functional ability with
computer calculation may help me understand and do math and other
subjects.
I hate MATLAB.
I don't see why we have to learn to use the computer in math
class."

By offering this pardon we are neither admitting nor denying any
guilt on the part of our people or ourselves. It is just the
right thing to do. Lets just get this MATwater scandal behind us
and look forward to the best 21st century of computer-confident
graduates that we can get.
