MATLAB OOP: Can't we just be friends?

I've been using MATLAB's object-oriented programming features to
build a set of classes to represent my data. Essentially, the way
the data is structured, many of the classes are containers that
encapsulate instances of other classes. Sometimes it would be
advantageous for the container classes to access fields of the
encapsulated objects they hold. However, they are not allowed to do
so because "access to an object's fields is only permitted within its
methods."

I could, of course, write accessor methods for each situation that
calls for a container or iterator class to access data from a
subordinate object. However, the classes are so closely related that
it is not an unreasonable thing to want to permit the container or
iterator class to have direct access to the internal fields of the
subordinate object. In the C++ world, one would make the two classes
"friends" and this would allow the access. Is there an equivalent
operation in MATLAB's class system that will permit one class to
access the fields of another class?
