Hello everybody, there is just one simple question that comes across my mind and I can not figure it by myself, so I would like to put it here and see your understanding or opinion about it.
The question is: is matlab basic variable such as double, char object?
When I try to do some object operations such as getting its properties or the methods it can do, I got response which says that those variables are not class, but when I do the whos, it shows that those variables have class. How can I understand that?
Thanks for your opinions.

All variables have a "class". But not all variables are objects from an OOP class defined with classdef. I think what you are trying to do is treat regular objects like doubles and char as if they are objects from an OOP class defined with classdef, which they aren't.

Yes, variables created as one of the pre-defined classes such as double and char have their own pre-defined methods of creation and usage. They are not OOP classdef objects.
