1.  Have you tested with development branch of octave?  Does the disp 
work there?

-> Yes, I did, as you mentioned, that I should work with development version.

2.  Under "first steps" on the wiki, making "2*f" work is suggested. 
Perhaps that is a good first step?

-> Yes, I am working on it. But as only 2 weeks are left for the deadline of 
project proposal, so for now I am focusing more on preparation of proposals. 
So, can you please help me with this by answering questions related to proposal 
in the previous mail.

Thanks,
