If you're intent on doing this kind of thing from scratch, I'd suggest that you begin with a basic numerical analysis book that treats finite differences and the Crank-Nicolson method. It would also be a good idea to start with a simpler problem, something like dy/dt == d^2y/dx^2 + y(1-y) , 0 < x < 1, y(t,0)= 0, y(t,1) = 1, y(0,x) = x^2. On the other hand, you may want to look at the ReactionDiffusionLab package found here: http://www.math.armstrong.edu/faculty/hollis/mmade/RDL/ With it, you can solve problems such as the one you have, but in two space dimensions instead of one. ----- Selwyn Hollis http://www.math.armstrong.edu/faculty/hollis
