HELP needed on how to use symbols in FREEMAT?

[PRO]

Hello I am a student and new to FREEMAT, I have worked before in
MATLAB and I used a command line "syms t1, t2, t3" to declare symbols.
I further used them in trigonometric functions (ex: sin(t1) ). This
command line however does not work in FREEMAT and after searching the
help file I couldn't find much to it :-?.
What is the command line for what I am trying to do in FREEMAT?

I request QUICK HELP thanks!

The symbolic math toolbox in MATLAB is based on the Maple kernel - FreeMat doesn't have this functionality. If you want an open-source algebraic solver, there are several packages out there (maxima is one). if you assign ti a value (e.g.: t1 = 2*pi;), then sin(t1); should return a value as expected. Hope this helps.

Thanks it looks like you gave me a good hint but how do I multiply two
matrix es in maxima?

Google matrix multiplication maxima.

It took me 5 minutes to learn how to introduce matrices and multiply
them :P and 5 hours to learn to press shift+enter :D!
