ca_mat_fflu
Synopsis
#include <flint/ca_mat.h>int ca_mat_fflu(slong * rank, slong * P, ca_mat_t LU, ca_t den, const ca_mat_t A, int rank_check, ca_ctx_t ctx)sourceLike ca_mat_lu, but computes a fraction-free LU decomposition with Bareiss's algorithm and writes its denominator (the last pivot) to den. Although no divisions by pivots that do not cancel exactly are performed, fractions can appear in the entries since the symbolic simplification of exact quotients is not complete.
