Ok, so 2022a release still only runs via rosetta 2, no native support for m1 -- huge dissapointment. My question is, more to verify, if I call Python using in-process will it also run via rosetta? How about out-of-process calls?

Thanks

Hi Robert

In case of MATLAB R2022a, when calling Python in-process from MATLAB, it operates within the MATLAB process. As MATLAB is under Rosetta 2, the Python code also executes under Rosetta 2.

And when calling Python out-of-process, it initiates a separate Python process. This process can run natively on M1 hardware on ensuring compatibility of python libraries for ARM execution.

Beginning with the MATLAB R2023b release, MATLAB offers native support for Apple Silicon.

You can refer to the following MathWorks documentation links to know more about directly calling python functionality from MATLAB and out of process execution:

You can refer to the following MathWorks documentation link to know more about versions of python compatible with MATLAB products by release:

Hope this helps!
