Code generation failed in Simulink

Hello everyone !

I am working on Simulink/Stateflow and I don't manage to operate it. Whatever the model is, I have the same error message

For exemple, in this case, I just put a Matlab function to multiply by 2 the input.

I searched for rtwtypeschksum.mat file but I didn't find it. Actually, I don't know why it does not work.

Did some have the same problem ?

Best regards

It appears that one of the compiler options somehow got set to refer to a .mat file.

Try using

mex -setup C

to reset the options.

mbuild -setup

might be needed as well.
