2nd order ode on a non-rectangular region

Hi. I have a 2nd order pde r*f(x,t)=a1*x*df/dx + a2*x^2*d^2f/dx^2 + (x-c)df/dt (everything other than x and t are parameters), and I know the value of the function f f(x0,t) for each t in [t1, t2] and x0 given, and also f(g(t), t) for each value t in [t1, t2] (g is a given function). I need to solve for the value of the function for t in [t1, t2] and for x < g(t). Is there any embedded matlab tool that I can use to solve this? I wanted to use pedpe, but this one requires rectangular region. Any ideas on other ways to solve this? Thanks a lot!
