Matlab plot 3d matrix.

Aug 8, 2014 · 2. I don't understand how would you like to display covariance on a 3D plot. I think what you are looking for is pca , it would give you the three vectors corresponding to maximum variance in your 3D scatter plot. You can then determine the variance along each of those vectors and plot an ellipsoid which represents sort of a confidence region.
