Polynomial Multiplication

Hello,

I have such a polynomial P(x,y) = Q(x)*R(y) +S(x)*T(y)
with Q,R,S and T some linear polynomials.

I would like to get the coefficients of P(x,y)^n with n a given integer. Is it possible to get these coefficients with Matlab ?

I know that you can get the coefficients of A(x)*B(x) using conv. But what about with two variables x and y ?

Best regards,

H.
