PolynomialTraits_d::Invert

Definition

This AdaptableUnaryFunction inverts one variable in a given PolynomialTraits_d::Polynomial_d, that is, for a given polynomial $$p it computes $$x^degree(p)p(1/x).

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 inverts the order of the coefficients with respect to the specified variable.

result_type	fo ( argument_type p )	Returns $$xdegree(p)p(1/x), where x refers to the outermost variable $$xd-1.
result_type	fo ( argument_type p , int i )	Return $$xdegree(p,i)p(1/x), where x refers to the variable $$xi. Precondition:  $$0 i < d
