I have a SimuLink model that contains an embedded function. when I tried to launch simulation, I got this error "Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks. Use 'mex -setup' to select a supported C-compiler."
I had chosen a compiler: Microsoft Software Development Kit (SDK) 7.1 in C:\Program Files (x86)\Microsoft Visual Studio 10.0
I got always the same error when trying to run simulation.
I have MatLab 2012a Release and Windows 7 OS x64.
Thanks

In Matlab command write
mex -setup
choose your compiler
read the message from matlab

That should work. I'm assuming you've verified that the compiler is installed correctly and works separately from MATLAB or Simulink, and that you ran mex -setup and it didn't error. If so, I recommend contacting tech support.
