how to read 'categorical' values from 'mxArray'?

I would like to read the categorical output of 'SeriesNetwork.classify(...)' with my C program. However, I found that 'mxArray' did not expose values of categorical array, right?

To better understand, are you asking are there any mex/mx APIs for categorical arrays.

You can’t create categorical arrays with mxArray API, as there is no categorical in the mxClassID:

I haven’t tried yet, but you should be able to pass such an array to your MEX file from MATLAB and use mexCallMATLAB in your MEX file to invokes its methods.
