cell arrays: cat vs []

[Sam Sirlin]

I'm not sure quite what the relation is between cat and [], but in
matlab 6.5.1 [] does catenation for cell arrays:

>> [cell(1,3); cell(2,3)]
ans = 
     []     []     []
     []     []     []
     []     []     []

while in octave it doesn't:

octave:40> version
ans = 2.1.57
octave:41>  [cell(1,3); cell(2,3)]
error: octave_base_value::array_value(): wrong type argument `cell'
octave:41> cat(1,cell(1,3), cell(2,3))
ans =

{
  [1,1] = [](0x0)
  [2,1] = [](0x0)
  [3,1] = [](0x0)
  [1,2] = [](0x0)
  [2,2] = [](0x0)
  [3,2] = [](0x0)
  [1,3] = [](0x0)
  [2,3] = [](0x0)
  [3,3] = [](0x0)
}
 
This seems like it would be a nice extension...
