◆ operator()() [1/2]

template<class OutputIterator >
OutputIterator AlgebraicKernel_d_1::Solve_1::operator() ( AlgebraicKernel_d_1::Polynomial_1  p,
bool  known_to_be_square_free,
OutputIterator  res 
)

Computes all real solutions of \( p\), and copies them as objects of type AlgebraicKernel_d_1::Algebraic_real_1 in res.

The bool known_to_be_square_free indicates whether \( p\) is known to be square free. Each root, though it might be a multiple root, is reported only once.

◆ operator()() [2/2]

template<class OutputIterator >
OutputIterator AlgebraicKernel_d_1::Solve_1::operator() ( AlgebraicKernel_d_1::Polynomial_1  p,
bool  known_to_be_square_free,
AlgebraicKernel_d_1::Bound  l,
AlgebraicKernel_d_1::Bound  u,
OutputIterator  res 
)

Computes all real solutions of \( p\) in the closed interval \( [l,u]\), and copies them as objects of type AlgebraicKernel_d_1::Algebraic_real_1 in res.

The bool known_to_be_square_free indicates whether \( p\) is known to be square free. Each root, though it might be a multiple root, is reported only once.
