From: Herve on 27 Jul 2010 08:08 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.
