Thanks Jaroslav. Then I will do..
Question:
- There are a LBGFS codes out in the GNU community should we deal with it as
well?
- I used parameters as options however as I see fminunc uses a struct for
transmitting options. What is the preferable way?
- Shell we stick to texinfo coding style, in order to investigate in the hope
that once we will have a nice book generated from
octave-core and -forge functions out of the code?
- Ubuntu and other distros generate exteme number of .deb packages from the
octave-forge. How do you see?Should it be like this?
I would expect it to be in strict sync with the octave forge if there is a way.
