Using eye as in [A eye (2)]

[John B. Thoo]

Hi.  I have a newbie question.

If I define

A = [1,3;1,2]

and

D = eye (2)

then I get as expected

octave-3.2.3:20> [A D]
ans =

   1   3   1   0
   1   2   0   1


But [A eye (2)] does not give the same thing:

octave-3.2.3:21> [A eye (2)]
error: number of rows must match (1 != 2) near line 21, column 5
octave-3.2.3:21>

What am I not understanding?  TIA.

---John.
