vecpp :: Vec<typename, size_t>

vecpp::dot(vecpp::Vec)

template<typename T, std::size_t L>
constexpr T dot(const Vec<T,L>& lhs, const Vec<T,L>& rhs);

Returns the dot product of the thw argument vectors

Parameters

Argument	Role
lhs	The first vector operand
rhs	The second vector operand

Return value

The dot product of the passed vectors.

Example

#include "vecpp/vecpp.h"
#include <cassert>

int main() {
  using fVec2 = vecpp::Vec<float, 2>;

  fVec2 a = {3.0f, 0.0f};
  fVec2 b = {1.0f, 1.0f};

  float dot_val = dot(a, b);
  assert(dot_val == 3.0f);
}
