Is it possible to solve a non-linear elliptic PDE using pdepe? In my equation i have the elliptic terms d2u/dt2 and d2u/dx2, and also du/dt.
Thanks in advance.

Most likely you will need to introduce an auxiliary variable, v and equation du/dt = v since pdepe does not handle d2u/dt2 terms directly. So the answer is yes but it still depends on the particular form of your pde
