Synopsis
#include <flint/fmpz_mod_vec.h>void _fmpz_mod_vec_dot(fmpz_t d, const fmpz * A, const fmpz * B, slong len, const fmpz_mod_ctx_t ctx)sourcevoid _fmpz_mod_vec_dot_rev(fmpz_t r, const fmpz * a, const fmpz * b, slong len, const fmpz_mod_ctx_t ctx)sourceSet the output to \sum_{i} A_i B_i, respectively \sum_i a_i b_{\mathit{len} - 1 - i}, modulo n.
The sum is computed exactly with _fmpz_vec_dot (respectively _fmpz_vec_dot_general) and reduced once, so the entries may in fact be any integers.
