fmpz_poly_mat_nullspace
Synopsis
#include <flint/fmpz_poly_mat.h>slong fmpz_poly_mat_nullspace(fmpz_poly_mat_t res, const fmpz_poly_mat_t mat)sourceSets the first n - r columns of the n \times n matrix res to a basis of the right nullspace of the m \times n matrix mat over \mathbb{Q}(x), with polynomial entries, and returns n - r; the other columns are set to zero. The basis is read off from fmpz_poly_mat_rref.
