Polymul

polymul(x, y)

x, y are vectors

The input arguments x, y define two polynomials where the elements of the vectors are the coefficients in descending powers of the defined polynomial. polymul(x, y) return a vector which contains the coefficients of the product polynomial of the two polynomials

Input

Output
