Coding Two Dimensional PDE

Hi All,

I have equations as attached. I want to know how I code it in Matlab. If you can point me out to some simple code example that would be really appreciated. Would anyone please help?

What is your domain of integration ?

What are your boundary conditions ?

There seem to be two unknown functions, but only one differential equation ...
