I am currently using Matlab student version. But I always hear people that is deep involved in this topic programming in Fortran. Matlab is a little bit limited in memory capacity.

The party line is that Matlab is also SLOW in execution speed when compared to a compiled code (fortran, C, etc).

There was a discussion on this forum a couple of months ago on this subject. You might try to find it in the archives.

It was suggested that development be done on Matlab using 2-d problems, coarse meshes. When the ideas are clear and demonstrated to work, then code it up in a language that you can compile to run real problems.

Just a comment - Matlab CAN be compiled as well, but you need to pay for the compiler, of course. This could well be a way, but you must ask your Matlab supplier, how much will the compiler cost you.

Matlab solvers seem fast and have probably been optimized. I find that the assembly process is rather slow in Matlab and creates a bottleneck for me. The integrated graphics is convenient for development.

Overall, I agree with Jim Park, Matlab is great for exploring new ideas, but is too slow to be recommended for for large problems.

From all the inquiries about codes, it is too bad there is no open source movement to develop a set of open source, free codes. There could not be just one because it would be too complicated for beginners and probably not comprehensive enough for engineering and special purpose work.

But, if there was a compatible code base in Fortran and C++ that integrated existing open source sparse matrix representations and solvers, graphics, mesh generator, and input-output subroutines/classes/methods, that would be a great help.
