graph, digraph and table are MATLAB objects (meaning they are implemented as .m files). There is no C++ syntax to access such objects through mex files.

I discovered this thread while googling for the same question as Lightonz. It appears there is a way to do this now using matlab::engine::MATLABEngine::setProperty and matlab::engine::MATLABEngine::getProperty member functions.
