Operations

Let f and g be two RingElem values in a polynomial ring P. Let x be the index of an indeterminate from P.

• discriminant(f) -- f returns a RingElem (in the coefficient ring) being the discriminant of f.
• resultant(f,g) -- f,g returns a RingElem (in the coefficient ring) being the resultant of f and g.
• discriminant(f,x) -- returns a RingElem (in the same ring as f) being the discriminant of f wrt x.
• resultant(f,g,x) -- returns a RingElem being the resultant of f and g with respect to the indeteminate x.
• SubresultantSeq(f,g,x) -- returns a vector<RingElem> being the subresultant sequence of f and g with respect to the indeteminate x.
