Detailed Description

template<typename _Tp, int cn>
class cv::Vec< _Tp, cn >

A short numerical vector.

This template class represents short numerical vectors (of 1, 2, 3, 4 ... elements) on which you can perform basic arithmetical operations, access individual elements using [] operator etc. The vectors are allocated on stack, as opposite to std::valarray, std::vector, cv::Mat etc., which elements are dynamically allocated in the heap.

The template takes 2 parameters:

  1. _Tp element type
  2. cn the number of elements

In addition to the universal notation like Vec<float, 3>, you can use shorter aliases for the most popular specialized variants of Vec, e.g. Vec3f ~ Vec<float, 3>.
