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.
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. |
