PolynomialTraits_d::Negate

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.
