This solver is not generic and solves just one problem. However, it should be easy to adapt it to different problems. Not tested with Octave.
Run the FreeFEM++ (examplemesh.edp) file in /src and to obtain the mesh file. It's also included pre-compiled in the same folder.
Then run the femsolver.m MATLAB file for analysis, and output.
To change the number of elements used for analysis, change the m value in the FreeFEM++ file, and rerun.
