New subject: Fwd: gf undefined - ( my error ? or distribution specific)

29 Jul 2013


      Any fedora 17 octave user with communication installed able to use gf() ?
###########################################################
...
pkg load communications
octave:2> I = gf([1,0,0,0;0,1,0,0;0,0,1,0;0,0,0,1])
error: `gf' undefined near line 2 column 5
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.

I looked at several examples and I seem to be doing the right thing.
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
...
yum log

Jul 28 20:36:01 Installed: octave-communications-1.1.0-5.fc17.i686
rpm -V octave-communications shows no problems?
After "pkg load communications" do the paths from the rpm show up in
the Octave runtime path?
octave:1> pkg load communications
  octave:2> paths = strsplit (path, ":");
  octave:3> paths (!cellfun (@isempty, regexp (paths, "communications")))

  }

  'gf' is a function from the file
