Synopsis
#include <flint/fmpz_mat.h>void fmpz_mat_scalar_divexact_fmpz(fmpz_mat_t B, const fmpz_mat_t A, const fmpz_t c)sourcevoid fmpz_mat_scalar_divexact_si(fmpz_mat_t B, const fmpz_mat_t A, slong c)sourcevoid fmpz_mat_scalar_divexact_ui(fmpz_mat_t B, const fmpz_mat_t A, ulong c)sourceSets B = A / c, assuming that c \ne 0 divides every entry of A; the result is undefined otherwise. Aliasing is allowed.
fmpz_mat_scalar_divexact_fmpz precomputes the division by c once for all entries (see _fmpz_vec_scalar_divexact_fmpz_strided), which makes it much faster than entrywise division when c is large.
