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(4, 1, CV_8UC1, cv::Scalar(1)),
                                      cv::Mat(4, 1, CV_8UC1, cv::Scalar(2)),
                                      cv::Mat(4, 1, CV_8UC1, cv::Scalar(3)),};

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

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

src

input array or vector of matrices. all of the matrices must have the same number of rows and the same depth.

dst

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