[CODE SNIPPED]

Couple of things:

- You're posting to a Python newsgroup, not a Java newsgroup.  Try
comp.lang.java , if there's a strict requirement to do this in Java.

- Curiosity compels me to ask, however: what type of class is this assignment
for? Is this a "Programming in Java" class?  If so, you might re-read your
question and note that it _seems_ from its unqualified generality that you're
asking others to do your homework for you.

Now, I doubt you're asking others to do your homework for you.	Assuming I'm
correct then, please clarify this one critical issue: is one of the
requirements of your assignment that you reimplement an existing C
implementation of a matrix multiplier in Java, or may you use any other
language?  If the latter, Armin's advice (use JPython to compile a Python
implementation down to Java bytecode, then run as a "Java applet") satisfies
the letter of the law.

I would also suggest that you simply not _read_ the reference C
implementation.  This is a learning exercise, right?  You'll get much more
learning out of this exercise by: - getting an explicit problem statement
from your instructor, in detail - getting explicit programming guidelines
(choice of language, etc.) - getting the algorithm for a matrix
multiplication (this is language independent) - implementing the algorithm
from scratch in your target language, *without confusing the issue by trying
to reverse engineer an existing implementation written in another language*

That last point above is crucial.  The way you solve this problem in Python
is different from the way you solve it in C. Hint: use Python's built in
'list' datatype. Big hint: use nested 2-element lists or tuples. You'll write
less code.

Again, if you get the instructor to strictly
agree that you can do this as a "Java applet", regardless of the language
the bytecode is compiled from, you can use Python to do this very quickly
and easily.

Good luck,
Russell
