Using Level-2 classes with r2011b

Hello,

I have created some level-2 classes for code generation purpose. Now, I can create myclass.parameter and myclass.signal. My class inherites from AUTOSAR class in MATLAB. I used MATLAB r2013b to test the level-2 classes, that I created by writing Parameter.m, Signal.m and csc_registration.m.

Is it possible to use the level-2 classes under MATLAB r2011b? I know that I can use level-1 classes under r2011b, but I need level-2 classes.

If it is not possible to use them, does any workround exist for this problem?

Best regards,

Daniel.
