For the Code Inspector to pass correctly, we need to make sure that the model is compatible for the inspection process. We can do this using the option 'Check this model' in the Simulink Code Inspector Dialog box. If the model passes all the checks in the Model Advisor, only then the model is compatible for code inspection. If the model is not compatible, the report would show the warnings 'Unable to process' or 'Partially processed'.
At my end, the check 'Check usage of Code in MATLAB Functions' shows a warning 'unsupported MATLAB code was found in MATLAB functions'. In the warning message, it also shows which parts of the MATLAB Function are not compatible. I would recommend modify the MATLAB Function in the model such that it is compatible with the Code Inspection.
