octave-3.0.5 behavior:

octave:1> foo{1} = "a"
foo =

{
  [1,1] = a
}

octave:2> foo{2} = "ab"
foo =

{
  [1,1] = a
  [1,2] = ab
}

octave:3> foo{3} = "abc"
foo =

{
  [1,1] = a
  [1,2] = ab
  [1,3] = abc
}

octave:4> foo{4} = [1 2 3 4; 5 6 7 8; 9 10 11 12]
foo =

{
  [1,1] = a
  [1,2] = ab
  [1,3] = abc
  [1,4] =

      1    2    3    4
      5    6    7    8
      9   10   11   12

}

octave:5> numel(foo{:})

Invalid call to numel.  Correct usage is:

 -- Built-in Function:  numel (A)


Additional help for built-in functions and operators is
available in the on-line version of the manual.  Use the command
`doc <topic>' to search the manual index.

Help and information about Octave is also available on the WWW
at http://www.octave.org and via the address@hidden
mailing list.
