absl::c_inner_product

Synopses

Declared in <absl/algorithm/container.h>

Container-based version of the <numeric> std::inner_product() function to compute the cumulative inner product of container element pairs.

template<
    typename Sequence1,
    typename Sequence2,
    typename T>
constexpr
std::decay_t<T>
c_inner_product(
    Sequence1 const& factors1,
    Sequence2 const& factors2,
    T&& sum);

Overload of c_inner_product() for using binary operations other than operator+ (for computing the accumulation) and operator* (for computing the product between the two container's element pair).

template<
    typename Sequence1,
    typename Sequence2,
    typename T,
    typename BinaryOp1,
    typename BinaryOp2>
constexpr
std::decay_t<T>
c_inner_product(
    Sequence1 const& factors1,
    Sequence2 const& factors2,
    T&& sum,
    BinaryOp1&& op1,
    BinaryOp2&& op2);
