How can I modify properties of `KalmanFilter`

Summary of your issue

KalmanFilter contains only getters (which returns new Mat each call) to all properties ex. TransitionMatrix or ProcessNoiseCov.

How can I modify those properties?

Environment

Ubuntu 18.04.3 LTS

Example code:

kalman.TransitionMatrix = new Mat(2, 2, MatType.CV_8U, new double[,]
{
    {1, 1},
    {0, 1}
});

What did you intend to be?

I should be able to set state of filter.

Complete example of setting filter’s state: https://docs.opencv.org/trunk/de/d70/samples_2cpp_2kalman_8cpp-example.html#a12

In OpenCV all matrices are public. https://github.com/opencv/opencv/blob/master/modules/video/include/opencv2/video/tracking.hpp#L360
