Increment a class property everytime calling a class method

Hey Guys,

I am trying to write a program which read different txt-files, whenever I call a class method.

So for example

%%%%%%%%%%%%
classdef Foo
properties
      counter=0;
    end
methods
% Standard constructor
function1
%function 2 (should read the text file and increment the counter property)
function 2 
counter=counter+1;
for i=counter to counter+N..
readfile
end 
counter = i;
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

So basically when I'm calling function 2, it reads the file until a number N. After it read it, it sets the property counter to the last index. And whenever I call the function 2 again, it should read the files starting from counter+1. Is there a way to work with set/get. I don't understand the documentation tbh

Thank you guys

subclass from the handle class (default is value class), and you can update properties of the instance without explicitly overwriting the instance. It's not clear what your loop is doing (N is not defined), i dont think you need it...or it might make more sense to loop from outside the method.

classdef Foo < handle
    properties
        counter = 0
    end
    
    methods
        function this = Foo(varargin)
            % constructor
        end
        function readFile(this,file)
            % do whatever you need to do
            this.counter = this.counter + 1;
        end
    end
end
