RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

    std::vector<cv::Mat> matrices = { cv::Mat(1, 4, CV_8UC1, cv::Scalar(1)),
                                      cv::Mat(1, 4, CV_8UC1, cv::Scalar(2)),
                                      cv::Mat(1, 4, CV_8UC1, cv::Scalar(3)),};

    cv::Mat out;
    cv::vconcat( matrices, out );
    //out:
    //[1,   1,   1,   1;
    // 2,   2,   2,   2;
    // 3,   3,   3,   3]
 

vconcat(src: MatVector, dst: Mat): void;

src

dst

Output destination, filled by the native operation. output array. It has the same number of cols and depth as the src, and the sum of rows of the src. same depth.
