vecpp :: reference :: Mat<typename, std::size_t, std::size_t>

vecpp::operator-(vecpp::Mat)_unary

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

Returns the negated version of the vector

Parameters

Argument	Role
rhs	The vector to negate

Return value

A vector equivalent to rhs where operator-() has been applied to it element-wise.

Example

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

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

  fVec2 a = {10.0f, -5.0f};

  fVec2 b = -a;

  assert(b[0] == -10.0f);
  assert(b[1] == 5.0f);
}
