Details:

With MATLAB:

>> a={
{
1
2
}
{
2
3
}
}

a = 
    {2x1 cell}
    {2x1 cell}


With Octave:

octave> {
> {
> 1
> 2
> }
> {
> 2
> 3
parse error:

  syntax error

>>> 3
    ^


Arguably, the correct syntax might be:

octave:86> a={
> {
> 1;
> 2
> }
> {
> 2;
> 3
> }
> }
a = 
{
  [1,1] = 
  {
    [1,1] =  1
    [2,1] =  2
  }
  [2,1] = 
  {
    [1,1] =  2
    [2,1] =  3
  }
}


or

octave:91> {
> {
> 1
> 2
> };
> {
> 2
> 3
> }
> }
ans = 
{
  [1,1] = 
  {
    [1,1] =  1
    [2,1] =  2
  }
  [2,1] = 
  {
    [1,1] =  2
    [2,1] =  3
  }
}


but I'm still unsure whether the difference in behaviour is due to MATLAB
accepting an invalid syntax or a bug in the Octave parser.
