Matlab static variable that can be modified by super class and sub class?

I have following structure where I have a superclass and two subclasses

classdef A 
    properties
        staticvar
    end
end

And two subclasses of A

classdef B < A
    properties
        
    end
end

classdef C < A
    properties
        
    end
end

Is there a way I can use "staticvar" such that the "staticvar" value can be modified by any of the classes and its value is reflected when accessed by any of the class?

You mean you want all instances of the class and its subclasses to share the same copy of staticvar? If so, you can write the superclass like this.

classdef A 
    properties(Dependent)
        staticvar
    end
    
    methods 
        function val=get.staticvar(~)
           val=manage_staticVar;
        end
        function obj=set.staticvar(obj,val)
           manage_staticVar(val);
        end
    end
end


function out=manage_staticVar(val) %Not a class method - can be class-related function

 persistent p
 
 if nargin, p=val; end

 out=p;

end
