Really? so i can have a C++ class, and call it and its methods from an 
m-file in Octave, and have it persist like a real C++ object from one 
call of its methods to the next?

This is not possible with plain mex files in Matlab because you must 
create an instance of a C++ class which will be destroyed once the mex 
file completes (which is the problem that using handle classes in the 
linked example solves). As I understood it Octave has the same 
limitation, but since it does not yet have classdef, there is no way to 
do the same thing. I'd be very interested hear if there was though, or 
that I have misunderstood something about oct files.
