How to Automatically Compare Simulink Models

Is there a way to automatically produce a diff of Simulink models? I would like to be able to generate a report of the differences and have this shown by our code review tool so that it is possible to do simple reviews without loading the code in MATLAB.

I know it is possible to do this manually with MATLAB (see for Compare Revisions and How to Compare Models). Is this also available via the MATLAB API, and if so, could you point me to the documentation?

Thanks.

You can create an HTML or Word report of the differences between two Simulink models using the ‘comparison’ output argument of the visdiff function (R2017b or newer).

For example, you can try something like this

 >> comparison = visdiff(model1, model2);
 >> % Publish the results of the comparison to a file:
 >> reportFile = publish(comparison, 'Format', 'HTML', 'Name', 'myreport.html')

For more information, see the ‘Publish Comparison Report’ section of the visdiff documentation page:

Any alternative to this solution to make this work on R2016b?

Any way of using visdiff to compare rivisions of same model? (for-eg compare model1 from previous commit to current model1 version)
