[Octave-bug-tracker] [bug #44035] unable to subclass built-in types

[Mike Miller]

Follow-up Comment #3, bug #44035 (project octave):

No, numeric types or structs are not classdef classes in Matlab, even though
they do share a lot of properties with classdef classes. I would say yes to
comment #1, they behave like classdef objects in some cases, but they are not
actually classdef objects.

The 'isobject' function returns false for numeric types, logical, char, cell,
struct, and function handles for example, so they are not classes in that
sense. But they can have overridden methods, they can be used with the
'methods', 'properties', and 'metaclass' functions, and can be subclassed.
