Details:

When an array of more than two dimensions is displayed, 'ans' is used for the
name of the variable:


octave:15> a = rand (3,3,2)
a =

ans(:,:,1) =

   0.462941   0.802606   0.761311
   0.922112   0.916468   0.987126
   0.963205   0.593986   0.087091

ans(:,:,2) =

   0.42108   0.69784   0.62200
   0.16416   0.16271   0.11518
   0.41170   0.75955   0.64193


This is a little bit misleading as there is no variable 'ans':


octave:16> whos
Variables in the current scope:

   Attr Name        Size                     Bytes  Class
   ==== ====        ====                     =====  ===== 
        a           3x3x2                      144  double

Total is 18 elements using 144 bytes


In comparison, Matlab displays the following:


>> a = rand (3,3,2)

a(:,:,1) =

    0.2498    0.2543    0.3066
    0.9429    0.8063    0.4474
    0.6879    0.9031    0.8050


a(:,:,2) =

    0.9369    0.2796    0.9091
    0.1507    0.6469    0.1390
    0.5728    0.2529    0.1284
