— Function File: [q, r] = polyderiv (b, a)

Return the coefficients of the derivative of the polynomial whose coefficients are given by vector c. If a pair of polynomials is given b and a, the derivative of the product is returned in q, or the quotient numerator in q and the quotient denominator in r.
