I don't think anyone has done any work on implementing categorical
arrays. You are certainly welcome to start working on that if you want.
That also means it may take some effort to find interested parties to
give you some feedback and testing.

If you want to develop full support for this data type, it looks like
there is plenty of work to do beyond the 4 functions you listed:

https://www.mathworks.com/help/matlab/categorical-arrays.html
https://www.mathworks.com/help/matlab/matlab_prog/other-matlab-functions-supporting-categorical-arrays.html

I'm sure you've seen this stated already, but be sure not to read or use
any Matlab files at all, other than the publicly accessible docs.
