It seems that after parsing an input sequence with addOptional and
addParameters (here addRequired is not represented), while in Matlab the
parameters in the output Results field follow the alphabetical order, in
Octave follow the code insertion order:


% defaults = {'a',1,'b',2,'c',3,'z',4}
inputs = {30,'b',20,'a',10}
p = inputParser()
p.addOptional('c',3)
p.addOptional('z',4)
p.addParameter('b',2)
p.addParameter('a',1)
p.parse(inputs{:})
p.Results
% orderfields(p.Results)


Matlab order:

  a = 10
  b = 20
  c = 30
  z = 4


Octave order:

  c = 30
  z = 4
  b = 20
  a = 10


Now, assumed that I prefer Octave solution (it's always possible to sort by
alphabetical order, while getting the original one is not possible), I'ld like
to know if there is a configuration option for this.
Otherwise, it would be a (minor) misalignment, maybe.
[In my code it generated some errors because the Results output was converted
to a cell array and compared with other results. Now I aligned Matlab and
Octave's output by explicitly sorting the output by fieldnames].
