Computes the polynomial subresultant of two polynomials p and q of type PolynomialTraits_d::Polynomial_d with respect to outermost variable. Let p= ∑_{i=0, … ,n}^{}p _{i} x^{i} and q= ∑_{i=0, … ,m}^{}q _{i} x^{i}, where x is the outermost variable. The ith subresultant (with i=0, … ,min {n,m}) is defined by
where p_{i} and q_{i} are set to zero if i<0. In the case that n=m, Sres_{n} is set to q.
The result is written in an output range, starting with the 0th subresultant Sres_{0}(p,q) (aka as the resultant of p and q).
 

 
computes the polynomial subresultants of p and q, with respect to the outermost variable. Each element is of type PolynomialTraits_d::Polynomial_d.
