[Octave-bug-tracker] [bug #60726] nargout for {} in subsref() method does not match MATLAB

[Fernando]

Follow-up Comment #7, bug #60726 (group octave):

I have identified two more cases where nargout in Octave is different from
nargout in Matlab. Applying the patch from file #56712 also eliminates the
differences in those two cases (as well as the case from comment #5).

To see the two cases, we can define this simple class:

classdef class_bug60726 < handle
  methods
    function varargout = subsref(obj, s)
      varargout = num2cell(repelem(nargout,max(nargout,1)));
    end
  end
end


In Octave:

octave:> x(1).a
ans = 0
octave:> x{1}.a
ans = 0


In Matlab (or Octave with patch from file #56712 applied)

>> x(1).a
ans = 1
>> x{1}.a
ans = 1


There might be more corner cases, and it may be debatable whether Matlab's
answer is better than Octave's, but I think it is good to increase
compatibility.

I am attaching a patch that includes the changes from file #56712 and also
some test cases.
