I have access to MATLAB through my University. Can anyone recommend any introductory texts on finite element methods which incorporate MATLAB? __________________ "It is a profound and necessary truth that the deep things in science are not found because they are useful; they are found because it was possible to find them."

Filling the matrix is a matter of calculating the coupling coefficients between elements based on the mathematical kernel for the physics under evaluation (look up Green's functions); usually simple for differential formulations, rather more complicated for integrals. Often the hardest part is getting a good mesh over the objects of interest. There are probably some good references for differential formulations, but I'm more familiar with integrals. Specifically electromagnetics, which is probably not what you're interested in since this is an audio forum, but you'll find general integral equation stuff by searching for the method of moments.
