I have a class myClass which inherits from the handle object and has a constant property:
classdef myClass < handle
properties(Constant)
myProp = 'abc';
end
end
I have a reference to the class: ref = @myClass
How do I retrieve 'myProp' from 'ref' without instantiating the class?

myClass.myProp
will give you the constant property, you don't need an instance of it.
ref = @myClass
is a function handle to the constructor of the class, not a reference to the class, but either way is irrelevant to getting a constant property.

I'm aware of myClass.myProp working, but that's not helping when I want to generalize the reference to any class in a 'super-class'. If @myClass is just a reference to the constructor though then it seems like it can't be done.

Matlab does not really have references. It would much easier to help you if we knew what it is you're trying to achieve.
