Any good MATLAB resources on the web?

I’ve used MATLAB a few times several years ago in my undergrad days, and don’t remember a damn thing. I have what is essentially a Fourier series for mass diffusion that I solved from a PDE and given boundary conditions, and I just need to get a time value for a given x-value and a final mass concentration value.

I could work it out by hand if I really had to using just the first few terms in the series, but it would be better to be able to use lots of terms, like MATLAB can, and a plot is also desirable, and that’s harder to do by hand.

Is there a good site that goes through doing this step-by-step? Or maybe a downloadable manual/PDF?

If it helps, the equation is:
C=1.5-Σ(n->∞)[2.6/nπ*(1+(-1)sup[/sup])*sin(100nπx)]

well, a good place to start is the web site:

Octave is an open source version if you want to go that route.
