hi, I am currently building my c++ program running with Simulink. I have tried the code I found from the website: https://uk.mathworks.com/help/matlab/matlab_external/run-simulink-simulation-from-c.html

However, it seems I've some problem when I run this code :

std::unique_ptr<MATLABEngine> matlabPrt = connectMATLAB(session);

When I run connectMATLAB() it gives me unhandled exceptions:
