I have created a multi-dimension array, but I am not getting how to display the value. I am getting dim value correct but row/col variable is -1. How to display the matrix content.
int arr[4] = {4, 3, 2,5}; Mat L(4, arr, CV_8UC(1), Scalar::all(0));
rows and cols only make sense in a 2d context, with higher dimensional Mat's you'll have to look at the size member like:
cout << L.size << endl;
4 x 3 x 2 x 5
also, there are only suitable print functions for 2d Mat's, but you may "slice" your multi-dimensional Mat into planes, and visualize / print out those:
Mat slice(2, 5, CV_8U, L.ptr<uchar>(3,2)); // last element, just as an example
cout << slice << endl;
[ 0, 0, 0, 0, 0;
0, 0, 0, 0, 0]
