I am trying to compare model versions and extract what is added/deleted/modified by querying the difference tree.
Edits = slxmlcomp.compare(ModelA, ModelB).
Is there a neat way to compare an empty model with a model? For instance, I want to compare a Simulink model file that doesnot exist before and a file newly added.

For comparing Simulink models, you can also use “visdiff” command which displays the differences between the two specified folders or files.
visdiff(‘model1.slx’,‘model2.slx’);
For more information regarding “visdiff “ command do refer the below documentation:
Compare two files or folders - MATLAB visdiff (mathworks.com)
Hope this helps!!

I am actually looking to do this programmatically where I am querying the difference tree to get what changed between before and after version of model. Hence I will need to do this using
Edits = slxmlcomp.compare(ModelA, ModelB).
The Edits Object (which is read only ) will have a left and right tree. I need the left tree to have practically nothing (or root only.) I have been doing the comparison by comparing the added file vs deleting content mathworks.com/help/simulink/slref/… . This way of comparison still leaves behind configuration being modified rather than added
