Assuming a member within a class has private access properties, i.e., GetAccess=private, if we use a "." type reference for that member in the overloaded subsref method, then the access property of that member becomes invalid at that point.--------------------- So, is there a good way here to allow users to both retain access control for properties and overload indexing methods?

Nope, not true. Even if you don't define a subsref method, private properties are still accessible through other class methods. This doesn't violate the idea of private access.

What you should be doing, probably, is to write your subsref method so that it checks whether the property is private before giving access to it.
