A Matlab Tutorial for Diffusion-Convection-Reaction Equations using DGFEM

We present a collection of MATLAB routines using discontinuous Galerkin finite elements method (DGFEM) for solving steady-state diffusion-convection-reaction equations. The code employs the sparse matrix facilities of MATLAB with "vectorization" and uses multiple matrix multiplications {\it "MULTIPROD"} to increase the efficiency of the program.
