Synopsis
#include <flint/nmod_poly_mat.h>int nmod_poly_mat_solve(nmod_poly_mat_t X, nmod_poly_t den, const nmod_poly_mat_t A, const nmod_poly_mat_t B)sourceint nmod_poly_mat_solve_fflu(nmod_poly_mat_t X, nmod_poly_t den, const nmod_poly_mat_t A, const nmod_poly_mat_t B)sourceFor a square A of dimension n and an n \times k matrix B, sets (X, den) with AX = \mathit{den} \cdot B and \mathit{den} = \det A, and returns 1 if A is nonsingular; returns 0 with den = 0 if A is singular. Both use fraction-free elimination. X may be A but not B.
