I have a base class and subclass inheriting from it. Base class has method A. Subclass overloads that method. I want to force the base class to use (only in some places) it's own method, not the one overloaded by subclass. Is there any way to do it?

Thank you

Hi Naum,

When you create an object obj of a superclass and then use obj to call the overloaded (or any) method of the superclass, the method defined in the superclass is called and not the one of the subclass.

Refer to this documentation for more information.

Hello Shraddha,

Sorry, but this does not help. What I want to happen is this: when super class has funcitons F1 and F2, and F2 calls F1, I want that F2 would call F1 of the SuperClass, not of the SubClass - in certain circumstances, when I tell it so.

Please, see the attached example classes. Both in SubClass and SuperClass the method F2 calls the method F1. In the subclass these methods first call the corresponding method of the SuperClass, which is the usual practice.

And this is what happens: when SubClass.F2 calls the SuperClass F2, the latter calls F1 of the SubClass. I want it to call F1 of the SuperClass. Maybe not always, but only when I want exactly this behavior. This is simple in C++. How can it be done in Matlab?

Thanks,

Naum
