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?

'gf' is a function from the file
