Octave is disributed under the terms of the GPLv3 license.

If your application can be considered "derivative work" of Octave,
it must be distributed under a GPL compatible license too.

I am personally under the impression that your setup might be
considered as "derivative work", but I am not a lawyer. 

If you want a professional opinion, I'd suggest you consider
using the FSF GPL compliance certification service:
