Matrix left division

edit

Hi, I would like to achieve left division A\B of cv::Mat matrices. I was looking for a solution and found one. My problem can be solved by using cv::solve method in a form cv::solve(A,B, result_matrix) but achieved result matrix has all element equals to zero, what is not a good result because I have checked correct solution of left division in MATLAB.

Have someone used cv::solve method for left matrix division and could share with an example code for matrices defined by dimension (3x3)?

Or maybe there is an other solution about I don't know...

Thanks in advance for help :)
