Follow-up Comment #3, bug #50359 (project octave):
Apologies, it is still not clear to me:
if
%!assert (isnull ([]), true)
%! x = [];
%! assert (isnull (x), false);
then assignment of [] to x or reading [] from x
changes the object.
Is this true?
Also from the documentation,
i cannot figure out,
what is meant by the difference between isnull and isempty.
isnull seems to imply isempty but not the other way round,
correct?
