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?
