Matlab simulink Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks. Use 'mex -setup' to select a supported C-compiler?

Question

I have a model in matlab simulink. I have installed matlab in D drive. When I run my model I get the following error: Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks. Use 'mex -setup' to select a supported C-compiler. This is not a syntax or semantics. How can I solve this? Thanks

You need a C/C++ compiler. Here is a list of MATLAB compatible compilers:

As an example, you can download MS Visual Studio for free:

After installation, open MATLAB and run: mex -setup

Select the compiler that you want (assume there is only one after you install one).

Should be all set.
