on a square 0<p<1, 0<q<1, with random initial data p,q. How can I do? Could someone help me please? I want to plot the solution for any initial data and find the difference beetween them. Thank you very much

Hi Emrys,
You may find the " pdepe " function in MATLAB useful for your application here. The equation that you wanted to solve falls under equation (1-3) of the "pdepe" function doc page for Initial-Value problems, but for your case a lot of the terms in the general equation is 0, as you have a simple PDE.
You may take a look at Example 1 of the page as the setup is similar to what you wish to achieve.
Thanks,
David
