Template class for short numerical vectors, a partial case of Matx.
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:
_Tp | element type |
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>.
It is possible to convert Vec<T,2> to/from Point_, Vec<T,3> to/from Point3_ , and Vec<T,4> to CvScalar or Scalar_. Use operator[] to access the elements of Vec.
All the expected vector operations are also implemented:
