Furthermore, when a std::vector<float> is used to initialize a cv::Mat, it is considered as a column vector, see heretemplate<typename _Tp> inline Mat::Mat(const std::vector<_Tp>& vec, bool copyData) : flags(MAGIC_VAL | traits::Type<_Tp>::value | CV_MAT_CONT_FLAG), dims(2...

To initialize an std::array, we can simply assign values to it at declaration. std::array<int, 5> n = {0, 1, 2, 3, 4}; std::array<int, 5> m {0, 1, 2, 3, 4}; As the length of the array needs to be known at compile time, we can declare the array and later initial...
