I think the questions are w.r.t using liboctave, an integral part of 
GNU Octave.

You can write your code as a 'oct' function in C++ and dynamically
load it for use, within Octave. It is not possible to use these libraries
as stand-alone, unless you want to compile a significant part of Octave
into your application.
