How can I find out if a class is a handle or a value class? Unfortunately I can't seem to figure it out. Take e. g. matlab.mixin.CustomDisplay. The documentation only says it's handle compatible, but not if it is itself a handle class. I need a class that inherits from handle and matlab.mixin.CustomDisplay. So if the latter is itself a handle class, inheriting from handle would be redundant, right?

You can use,
isa(obj,'handle')

It would be redundant to inherit both from handle and one of its subclasses. However matlab.mixin.CustomDisplay is not a subclass of handle, so it is not redundant in that case.
