Multiple instances of function with persistent variables

Hi, I have a function with persistent variables.

Is there anyway to run multiple instances of the function with different persistents?

The function is, and must be, Codegen compatible.

Thanks.

Yes, but that's called a "class". A class is an object that has methods (functions) and properties (variables). Look up how to create one. Each "instance" of the class has its own private set of variable/property values that can be different than in other instances of the class. And they stick around while you're not referring to the class and doing other things, so they're like persistent variables. They will have the same values when you get back to using them.

My function are already written and cannot be changed. Is there any way to wrap them somehow so that it would be possible?

Why can't you just copy your functions into the class's m-file? If not, then just make a method with the same name as your function and, as long as that function is on the search path, your method should call the same function as long as your function is called inside the method.

Attached is an example of a class, if you need one (though it's probably somewhat complicated for you). You can of course make a much simpler one.

Here's a simplified version:

classdef clsUserSettings
  %USERSETTINGS Summary of this class goes here
  %   Detailed explanation goes here
  
  properties (Access = private)
    MyVariable= '';
    TestFolder = '';
  end
  properties
    UserSettings;
  end
  
  methods
    %======================================
    % Constructor to take folders and set up properties.
    function US = clsUserSettings(macroFolder, testFolder)
      % Set up private variables.
      MyVariable = newMacroFolder;
      TestFolder = newTestFolder;
     end

       % =============================================
      % Method to take folders and set up properties.
      function US = func1(myInputVariable)
        fprintf('In func1\n');
        % Call other func1() in a separate file.
        US = func1(myInputVariable);
        % Assign the public property
        UserSettings.US = US;
      end
      
    end % Of the methods declarations  
  end % Of class definition.

That is just one example of how you could do it.
