Hello,
I dont understand everything in the example below. In my case, I have a 2D matrix (an image) of data and want to find two highest gaussians there. But this exemplary code does not relay on 2D image as an input. Instead, X has a size od 2000x2. What should I do to make it working on 2D square matrix?

Thanks, It seems it`s working. But how can I later extract coordinates of those gaussians from 1x1 gmdistribution?

You can't unless you do some classification into the model. A statistical model is just an idealised model of data that was input to create it. That input data is effectively lost and replaced by the model which is supposed to represent an approximation of that data by a well-defined model rather than just arbitrary data points.
