Detailed Description

template<class Domain>
class Givaro::Poly1Dom< Domain, Dense >

Class Poly1Dom.

Member Function Documentation

Poly1Dom< Domain, Dense >::Rep & setdegree ( Rep P) const
inline

Compute the degree of P.

Warning
this is an infamous function that may not leave P constant !!
Parameters
Ppolynomial
size_t & sqrfree ( size_t &  Nfact,
Rep Fact,
const Rep P 
) const

Sqrfree decomposition.

Decompose P such that: P = Fact[0]^0 * Fact[1]^1 * ... * Fact[P.degree()]^(P.degree()), with Fact[0] the leading coefficient. The array Fact must be allocated before calling the function. The size of Fact must be degP+1 is all factors should be computed. For more readeable version of the algorithm, see Geddes, p342.

Parameters
Nfact[in] the size of Fact
Fact[in] an array of dimension Nfact
Nfact[out] is the number of factor in the sqrfree decomposition
Fact[out] contains at most Nfact factors of the decomposition.
