Fwd: gf undefined - ( my error ? or distribution specific )
by Paul Campbell
Any fedora 17 octave user with communication installed able to use gf() ?

It should create an Identity matrix

Can anyone duplicate problem ?
I had sent this to the octave mailing list.
One opinion was that it might be distribution packaging problem.

Looks right to me:
octave:1> pkg load communications
octave:2> I = gf([1,0,0,0;0,1,0,0;0,0,1,0;0,0,0,1])
I =
GF(2) array.
Array elements =
1 0 0 0
0 1 0 0
0 0 1 0
0 0 0 1

rpm -V octave-communications shows no problems?
After "pkg load communications" do the paths from the rpm show up in
the Octave runtime path?

Fedora 20 Scientific planning
by Amit Saha
Hello everyone,
I would like to get us started with planning for the next release.
I will start by suggesting the new software that I plan to include in the next release:
- Python 3 and Python 3 versions of the libraries (we already ship)
- sympy (the Symoblic Math library for Python - http://sympy.org)
I also got started with packaging PiCloud library [1], but haven't done anything for a long time on it.
In case someone else is interested in taking it forward, let me know.
Also, I am quite unaware of generic libraries for science and Math from the ecosystem
of other languages (Perl, Ruby, Java). Would you like to suggest something?
What else would you like to see in the spin?

Best,
Amit.

Fedora 19 Scientific
by Amit Saha
Hi everyone,
If you have noticed that there is no release of Fedora 19 scientific, then that is because
I failed to fix a few problems on time. My sincere apologies for that.
So, to help you upgrade from Fedora 18 Scientific to Fedora 19 scientific, I have written some instructions in my post here [1].
I didn't have any trouble upgrading but that was also due to my overtly simplistic setup i believe.
[1] http://echorand.me/2013/07/04/upgrading-fedora-18-scientific-to-fedora-19...
I hope they are helpful and apologies once again.
Best,
Amit.
