PolynomialTraits_d::UnivariateContentUpToConstantFactor Concept Reference
Reference Manual » Concepts

## Definition

This `AdaptableUnaryFunction` computes the content of a `PolynomialTraits_d::Polynomial_d` with respect to the univariate (recursive) view on the polynomial up to a constant factor (utcf), that is, it computes the \( \mathrm{gcd\_utcf}\) of all coefficients with respect to one variable.

Remark: This is called `UnivariateContentUpToConstantFactor` for symmetric reasons with respect to `PolynomialTraits_d::UnivariateContent` and `PolynomialTraits_d::MultivariateContent`. However, a concept `PolynomialTraits_d::MultivariateContentUpToConstantFactor` does not exist since the result is trivial.
