Hello.
i have a problem in matlab producing a new program to compute the product of two polynomial but without using convolution. I really need help urgently.

eg.

Given 2 polynomials P1 and P2 where:
P1 = a0 + a1x + a2x^2 + ... + amx^m

P2 = b0 + b1x + b2x^2 + .... + bnx^n

p3 = sum of p1 and p2

eg. p1 = x
p2 = x + 2x^2 + 3x^3
p3 = x^2 + 2x^3 +3x^4

thank you very muchhh!!!!
