PolynomialTraits_d::SquareFreeFactorize

Definition

This Functor computes a square-free factorization of a PolynomialTraits_d::Polynomial_d.

A polynomial p is factored into square-free and pairwise coprime non-constant factors g_i with multiplicities m_i and a constant factor a, such that p = a · g₁^m₁ · ... · g_n^m_n.

The pairs (g_i,m_i) are written into the given output iterator.

This functor is well defined if PolynomialTraits_d::Polynomial_d is a UniqueFactorizationDomain.

Computes the square-free factorization of

p and returns the past-the-end iterator of the written range.

Precondition:

std::iterator_traits< OutputIterator >::value_type must be constructible from std::pair<PolynomialTraits_d::Polynomial_d,int>.

OutputIterator

fo ( PolynomialTraits_d::Polynomial_d p , OutputIterator it )

As the first operator, just not computing the factor
