| Well, maybe. The code produces:
| 
| "
| octave:1> cell_array = {[1,2;3,4], "foobar"; [5,6], {7, "foo", [8,9,10]}};
| octave:2>
| octave:2>   for elt = cell_array
| >     elt
| >   endfor
| elt =
| {
|   [1,1] =
| 
|      1   2
|      3   4
| 
|   [2,1] =
| 
|      5   6
| 
| }
| elt =
| {
|   [1,1] = foobar
|   [2,1] =
|   {
|     [1,1] =  7
|     [1,2] = foo
|     [1,3] =
| 
|         8    9   10
| 
|   }
| }

| and it can make sense to me if I consider cell array to be a 2D matrix with 
possibly  "awkward" (arbitrary type) elements.

| Should cell arrays be considered as 2D matrices ? If yes, which part of 
Octave documentation describes them as such ?
