How do I view the properties of an abstract class?
For a class such as classdef (Abstract) AbstractClassDemo properties (Constant) one = 1 two = 'two' end end I should be using something like meta.abstractDetails('AbstractClassDemo') which returns the error No abstract methods or properties for class AbstractClassDemo or no class AbstractClassDemo. To confirm to you that AbstractClassDemo is visible and accessible, I run AbstractClassDemo which returns Abstract classes cannot be instantiated. Class 'AbstractClassDemo' is declared as Abstract. What alternative options do I have? I can't find anything else I can do. Am I doing something wrong above? Should be simple right?

Call the properties function with the name of the Abstract class as input.
>> properties AbstractClassDemo
Properties for class AbstractClassDemo:
one
two
Alternately if you want additional information you could use either the ? operator or the meta.class.fromName function to create the meta.class object for the class. That object has an array of meta.property objects in its PropertyList property.
>> q = meta.class.fromName('AbstractClassDemo');
>> q = ?AbstractClassDemo;
>> propOne = q.PropertyList(1)
propOne =
property with properties:
Name: 'one'
Description: ''
