One way is via composition: (see http://en.wikipedia.org/wiki/Object_composition)

Let your two classes be class A and class B. Inside a property block of the class definition file for class A, include a variable, say bObj, that you intend to be an instance of class B. Then, in the constructor of class A, instantiate this instance of class B

 bOjb = B(...)

Assuming that method m() of class B is public, invoke it anywhere in class definition file for class A with

 bObj.m(...)

MATLAB: Super class get callers name

Found it. Just call this:

 me = class(obj);

this gives the name of the created subclass. I call it in the constructor of the superclass:

 function obj = mySuperClass() %constructor
   me = class(obj);
   obj.name = me;
 end

MATLAB: How to get a handle to a public method inside a class in MATLAB 7.8 (R2009a)

Suppose you have class called 'class_a' defined as follows:

classdef class_a
      methods
          function display_message(obj)    % public method
              disp('Hello, there!')
          end
          function h = get_handle(obj)    % return handle to method 'display_message'
              h = @display_message;
          end
      end
end

To get a handle to the method 'display_message', execute the following code:

obj_a = class_a;
h = obj_a.get_handle;
h(obj_a);
