Good to know. Thanks for checking.

Yes you can use the MEX API, but I do not recommend it. The MEX API is
clumsy (at best) and is not very nice to use (from a programmers point
of view). The native Octave C++ API is much nicer and is a lot more easy
to work with. So, I'd recommend going with that.
