Translation of Fortran into MATLAB code

I'm in need of a simple geochemical model written in matlab code, which simulates the gradual dissolution of spheres of particular minerals. The model is pretty simple consisting of linear equations, as well as one partial differential equation (see pdf for details). I have initial code written in fortran, however, I'd like to see this code translated into matlab m-files, possibly including a GUI interface (the design of which I can provide). Any questions feel free to contact me.
