Hi,

I noticed this behaviour of the inputParser class:


>> p = inputParser;
>> p.addParameter ('a', [])
>> p.addParameter ('b', [])
>> p.parse ('a', 1)
>> p.Results
ans =

  scalar structure containing the fields:

    a =  1
    b = []

>> p.parse ('b', 1)
>> p.Results
ans =

  scalar structure containing the fields:

    a =  1
    b =  1



This is inconsistent with Matlab behaviour and (to my understanding)
to the inputParser documentation:



>> p = inputParser;
>> p.addParameter ('a', [])
>> p.addParameter ('b', [])
>> p.parse ('a', 1)
>> p.Results

ans = 

    a: 1
    b: []

>> p.parse ('b', 1)
>> p.Results

ans = 

    a: []
    b: 1

>>
