MEX Platform Compatibility
If you obtain a binary MEX file from another source, be sure that the file was
compiled for the same platform on which you want to run it. The file extension reflects
the platform, as shown in this table. To determine the extension for your platform, use

macOS with Intel®
MEX files built on macOS with Intel are not supported on the Apple silicon platform using Rosetta 2.
It is not possible to run a 32-bit MEX file from within a 64-bit version of MATLAB®.
