Use Xcode c compiler on Apple M1 chip

Hello :)

I installed MATLAB and Simulink on a M1 Mac Mini. When trying to run a Simulink Model which previosly run under Windows 10, compiling fails.

mex -setup

returns "MEX configured to use 'Xcode with Clang' for C language compilation." which seems to be normal.

Is there any way to figure out if Simulink is able to access the compiler or compile c files from the MATLAB command window for testing?
