This material was produced in 1996 as part of Edmundo's master degree course. In 2002, this material was updated to work in version 4 of Mathematica. It contains a function that transforms a PDE in an ODE system by using the Generalized Integral Transform Technique [1, 2]. It's applicable to some coupled systems of diffusion equations in the form: D[u,t] == Div[k Grad[u]] - d u + p where u is a unknown variable that depends of x,y,z and t k,d depends of x,y,z p depends of x,y,z,t The work keeps in evolution. Contact the authors for suggestions and questions. To run the sample in the notebook, you must save the packages (.m) under "AddOns\StandardPackages\Calculus" in the Mathematica installation folder.
