Synopsis
#include <flint/fmpz_poly_mat.h>void fmpz_poly_mat_solve_fflu_precomp(fmpz_poly_mat_t X, const slong * perm, const fmpz_poly_mat_t FFLU, const fmpz_poly_mat_t B)sourceSolves AX = \mathit{den} \cdot B given the output FFLU, den, perm of fmpz_poly_mat_fflu for a nonsingular A, with fraction-free forward and back substitution. The sign of the permutation is not taken into account. perm must not be NULL, and X must not be B; both raise an exception.
