Simple Matlab diffusion modeling code and examples by Ramon Arrowsmith This is a simple matlab function that does diffusion modeling of profile development under transport limited and no tectonic displacement conditions. The MATLAB tool distmesh can be used for generating a mesh of arbitrary shape that in turn can be used as input into the Finite Element Method.
