are you looking for solutions in MATLAB or in R? This is the community for MATLAB.

and get back to your question, fitlme or fitglme in MATLAB has a bunch of different options for variance-covariance structure. the default is full cholesky. check https://www.mathworks.com/help/stats/fitlme.html#namevaluepairarguments where a full explanation is provided.
