Here is the documentation:

Your problem is a standard problem for pdepe. You should be able to manage the setup following the examples given in the link.

Best wishes

Torsten.

With the FEATool Multiphysics Matlab FEM Toolbox you can enter your own custom equations and PDE with an easy syntax (similar to how PDEs are written on paper).

It is not quote clear exactly how your equation looks like, but you could start with a convection and diffusion equation in the GUI and the press the Edit Eqn button to modify the PDE to what you really want. Afterwards you can also save the model as a m-file script and see how the fea model is defined.
