Help on Polynomial Convolution

Hi, 

I used Matlab to do numerical computing for a long time. Now I just
switched to Mathematica to do the symbolic computing on the same
problems. 

I want to represent a polynomial by it's coefficients as a List. For
example, the polynomial 1 + 2x + 3x^2  is represented as {1,2,3}.

In matlab, there is a function conv(Poly1,Poly2) to compute the
convolution of the two polynomials Poly1 and Poly2. Is there such
package in Mathematica?

I am grad. student on control system design. Where can I find the
related Mathematica packages on this topic?

Thanks
