If I have written a class MyClass, I can customize the behavior of expressions such as a.myProperty, a(4) where a is an instance of MyClass. As described in the documentation I do this by overloading subsref for MyClass.

But how can I in a similar way customize the behavior of the same operations applied to classes instead of class instances?

That is, how can I redefine the behavior of for example:

p = MyClass.MyStaticProperty;

Is there a static method equivalent to subsref?

Best regards, Joel

Why do you want that?

I am wrapping C++ code. I would like to be able to get and set static variables of the C++ class using a natural syntax.

Non-constant static properties are not supported in MATLAB. Here is a good explaination why: http://stackoverflow.com/a/6453124/1203683. For the same reason mentioned there (e.g. that you do not want to redefine A.B = C), I guess redefining subsref/subsasgn is impossible.
