CGAL 5.5.2 - Polynomial
PolynomialTraits_d::Negate Concept Reference

Definition

This AdaptableUnaryFunction computes \( p(-x)\) for a given polynomial \( p\).

Note that this functor operates on the polynomial in the univariate view, that is, the polynomial is considered as a univariate polynomial in one specific variable.

This functor is provided for efficiency reasons, since this operation just flips the sign of all odd coefficients with respect to the specified variable.
