I am not sure I understand this correctly. Can you give me an example of how 
can I pass around C++ types from/to octave command line? 

mex-handle basically stores pointers to C++ classes in octave matrixes, which 
you can the pass from the command line to C++ through mex files. "Translating" 
straight from the mex-handle into oct-files, if we wanted to do the same I 
guess it could be something like this:

------
MyClass foo;
Matrix mPointer(1,1);
*reinterpret_cast<MyClass**>(mPointer.fortran_vec())= &foo;
--->mPointer passed to octave command line as an output value
...
--->from octave command line, mPointer passed as an argument
MyClass* foo = *reinterpret_cast<MyClass**>(mPointer.fortran_vec());
------

This compiles, though I have not tested it. Is this correct? Is there a better 
way?
