Modified method from superclass isn't called

Hi,

I'm trying to extend the inputParser class, and hereby also extend the method parse() from that class.

Is it at all possible? The documentation seems to explain how to do this:

https://se.mathworks.com/help/matlab/matlab_oop/modifying-superclass-methods-and-properties.html

Here is my subclass with extended method:

classdef myInputParser < inputParser
    properties
        Extra
    end
    
    methods              
        % Class constructor
        function obj = myInputParser()
            obj.Extra.test = 0;
        end        
        
        % Extend inputParser superclass method parse()
        function parse(obj, varargin)
            % preprocessing steps
            
            parse@inputParser(obj, varargin{:});
            
            % postprocessing steps
            obj.Extra = obj.Results;
        end
    end
end

I create the object, and parse the input like so:

p = myInputParser;
p.parse(varargin{:})

When calling the parse() method on the object, it doesn't seem to call the extended parse() in the subclass.

What am I missing? Any help would be greatly appreciated.

When I restarted MATLAB, it worked.

After that I read about the command "clear classes", which might have helped as well. I had to clear the cache or something.

Yes, but the name of the constructor should be identical to the name of the class.

And the method

function parse(obj)
    % preprocessing steps
    parse@inputParser(obj);
    % postprocessing steps
    obj.Extra = obj.Results;
end

should read something like

function parse(obj,varargin)
    % preprocessing steps
    parse@inputParser(obj,varargin{:});
    % postprocessing steps
    obj.Extra = obj.Results;
end

Correct, I edited my original post.
