ca_mat_rref_fflu, ca_mat_rref_lu, ca_mat_rref
Synopsis
#include <flint/ca_mat.h>Sets R to the reduced row echelon form of A, writes the rank to rank and returns 1; returns 0, with meaningless outputs, if the rank cannot be determined. The fflu version starts from a fraction-free LU decomposition, the lu version (a wrapper of gr_mat_rref_lu) from an ordinary one, and the default version is a wrapper of gr_mat_rref.
