In 2.1.52, you could write

  Cell X;
  X(9) = ...;

and X would be resized to 10 elements before the assignment.  However,
this was not true for

  Cell X;
  X(9,9) = ...;

which would not resize first.

In 2.1.57, a Cell is just a thin wrapper for ArrayN<octave_value>, and
there is no implicit resizing for any of the operator()-style indexing
operations.  You need to set the size of the Cell before you use it,
same as for a numeric array or matrix object.

Perhaps this should be changed.  If you'd like to discuss it, please
start a new thread on the maintainers list.

Thanks,
