Does the MATLAB engine support creation of function handles?

I am using the MATLAB engine to run MATLAB code from C++. I have some C++ code that I would like to expose to the MATLAB user similar to what is possible when extending Embedded Python (see this link for a description). I am looking for a way to maybe use the ArrayFactory to create a function handle that would execute code in the C++ environment and then pass that function handle into the MATLAB workspace (probably using the setVariable command).

Is this possible? I can't find any documented support for function handles in the MATLAB engine.

It would sure be cool if I could do something like this. It would solve my immediate problem and open the possibility to all kinds of other interesting things in the future.
