the coefficient vectors can be transformed into the equivalent polynomials with the command
poly2sym
, resulting
in polynomial form. let's see:
the product polynomial will be:
>> pretty(poly2sym(conv(a, b)))
10 9 8 7 6 5 4 3
-14 x + 58x - 95 x + 43 x + 72 x + 60 x + 89 x + 15 x + 12 x
the quotient polynomial is:
>> pretty(poly2sym(q))
9 8 7 6 5 4 3 2
- 28 x + 118 x - 120 x + 251 x - 192 x + 180 x + 220 x - 45 x - 12
