fmpz_mod_mat_det
Synopsis
#include <flint/fmpz_mod_mat.h>void fmpz_mod_mat_det(fmpz_t res, const fmpz_mod_mat_t mat, const fmpz_mod_ctx_t ctx)sourceSets res to the determinant of the square matrix mat, and throws an exception if mat is not square. A wrapper of gr_mat_det; this works for every modulus, since a failed LU decomposition falls back to a division-free algorithm.
