PolynomialTraits_d::SquareFreeFactorizeUpToConstantFactor

Definition

This AdaptableFunctor computes a square-free factorization up to a constant factor (utcf) 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, such that a · p = g₁^m₁ · ... · g_n^m_n, where a is some constant factor.

The pairs (g_i,m_i) are written into the given output iterator.
The constant factor a is not computed.

This functor is well defined even though PolynomialTraits_d::Innermost_coefficient_type may not be a UniqueFactorizationDomain.

Operations

template<class OutputIterator>

OutputIterator

fo ( PolynomialTraits_d::Polynomial_d p , OutputIterator it )

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>.
