PolynomialTraits_d::TotalDegree

Definition

This AdaptableUnaryFunction computes the total degree of a PolynomialTraits_d::Polynomial_d.

Given a (multivariate) monomial the sum of all appearing exponents is the total degree of this monomial. The total degree of a polynomial p is the maximum of the total degrees of all appearing (multivariate) monomials in p.
For instance the total degree of p = x₀²x₁³+x₁⁴ is 5.

The total degree of the zero polynomial is set to 0. From the mathematical point of view this should be -inf, but this would imply an inconvenient return type.
