Re: How to initialize octave without read-eval-print loop?

[Fengbo Xie]

That's really what I'm looking for.
Michael, you even figured out the API methods name engOpen/engClose.
Actually the Matlab/Java bridge jmatlink implemented such API for Matlab, 
and JRI implented such API for R.
I'm looking forward the Octave One.
Is there anyone can give some tips on doing this?
