[Octave-bug-tracker] [bug #48656] overridden class subsref method may get wrong value for nargout

[Tasos Papastylianou]

Follow-up Comment #5, bug #48656 (project octave):

Please reopen this as a bug.

Compare the below octave output with the matlab output.


%%% Matlab (ignoring undefined variable errors):
x = [foo(), foo(), foo()];
x.whatever                    % ans = 3
[out] = x.whatever            % ans = 3
[~, out] = x.whatever         % ans = 2
[~, ~, ~, out] = x.whatever   % ans = 4

%%% Octave (ignoring undefined variable errors):
x = [foo(), foo(), foo()];
x.whatever                    % ans = 3
[out] = x.whatever            % ans = 3
[~, out] = x.whatever         % ans = 3
[~, ~, ~, out] = x.whatever   % ans = 3


You can see that, unless it's 0 or 1, matlab _does_ in fact take into account
the number of arguments requested.

(PS. I also note bug #48693 is related and open; the behaviour there is also
more compatible with matlab's behaviour here, though not identical since the 0
and 1 cases differ.)
