 CGAL 5.0.2 - Polynomial
PolynomialTraits_d::ScaleHomogeneous Concept Reference

## Definition

Given a numerator $$a$$ and a denominator $$b$$ this AdaptableFunctor scales a PolynomialTraits_d::Polynomial_d $$p$$ with respect to one variable, that is, it computes $$b^{degree(p)}\cdot p(a/b\cdot x)$$.

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

## Operations

result_type operator() (PolynomialTraits_d::Polynomial_d p, PolynomialTraits_d::Innermost_coefficient_type a, PolynomialTraits_d::Innermost_coefficient_type b)
Returns $$b^{degree}\cdot p(a/b\cdot x)$$, with respect to the outermost variable.

result_type operator() (PolynomialTraits_d::Polynomial_d p, PolynomialTraits_d::Innermost_coefficient_type a, PolynomialTraits_d::Innermost_coefficient_type b, int i)
Same as first operator but for variable $$x_i$$. More...
