MATLAB: Setter methods for dynamic properties

classdynamicprops setter

Hello,
I have been working with a class that has dynamic properties that I would like to have setter methods for. The problem is that I don't know how many or the names of the dynamic properties, so I want to have just one setter that takes the name of the property as an argument. However this breaks the part of MATLAB that determines whether or not you're in a setter function (so that when you set the variable it just sets the variable, instead of calling the setter recursively). Here's some example code that illustrates what I'm talking about:
classdef myClass < dynamicprops
    methods
        function obj = myClass()
            P = addprop(obj, 'myProp');
            P.SetMethod = @(o,p)SetProp(o,'myProp',p);
        end
          function SetProp(obj, propname, val)
              obj.(propname) = val;
          end
      end
  end
Now if you try:
x = myClass();
x.myProp = 7;
the method SetProp gets called recursively until MATLAB throws an error. Is there another way to go about this that I am missing? Thanks in advance.

What about overloading subsasgn
classdef myClass < dynamicprops
    methods
        function obj = myClass()
            P = addprop(obj, 'myProp');
        end
    function A = subsasgn(A, S, B)
      switch S.type
        case '.'
          SetProp(A, S.subs, B);
      end
    end
      
          function SetProp(obj, propname, val)
              obj.(propname) = val;
          end
      end
  end
