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 Yuan Zheng Dept of Mech. Eng. Umass, Amherst
