If you only want to communicate with Octave by passing text back and
forth between Octave and Perl, then you probably want to use something
like  That will allow you to use psuedo-ttys to control
Octave, which is (I think, correct me if I'm wrong) what the inferior
Emacs mode uses on most systems.

There is currently no easy way to embed the Octave interpreter in
another application.  That might be nice, but it's not really a high
priority project for me.
