How to interpolate PDE solution to cartesian grid

I can plot a solution using pdeplot(p,e,t,'xydata',u) but I want to interpolate my answer to a cartesian grid so that I can do other stuff with it. How would I do this?

Does you mean that results are in unstructured grid and you want them on structured grid?

interpolateSolution interpolates your solution to any set of points that you like. Create a Cartesian grid using the meshgrid or ndgrid commands.
