Linking MATLAB 2008 to C++

I am currently involved in a project in which data would be transferred from MATLAB to a C++ GUI created. The data would be processed and sent back to the GUI. I explored the options of MEX files and the MatLAB Compiler. Are there any methods for achieving "real time" data transfer?

MATLAB does not run on any real-time operating systems, so the concept of real-time with MATLAB is a little shaky. You could achieve a soft real-time system however, if you're willing to live with OS-related delays and you are not acquiring/transferring data to hardware that needs to meet a strict time-table.

You've already explored MEX-files and MATLAB Compiler. One other option that I can think of is calling into MATLAB as a COM Server or using the MATLAB Engine interface, which uses COM on Windows.

Thank you for your response. I will look into using the MATLAB engine as I see it is recommended for C++ programming.

Will I be able to access models stored in Simulink using the MATLAB engine approach?

Yes, you can use the Simulink command-line interface and execute commands using engEvalString.
