MATLAB enumerated switch statement always goes into first case

MATLAB enumerated switch statement always goes into first case

I am trying to use an enumerated class to dictate behaviour in a switch
statement in another class's constructor. So, what I have is the
following:
From my enumerated class:
classdef(Enumeration) MyScheme
enumeration
Scheme1, Scheme2, Scheme3
end
end
and then the class that uses this:
classdef MyClass < handle
methods
function c = MyClass(scheme, varargin)
switch(scheme)
case MyScheme.Scheme1
% Do stuff with varargin
case MyScheme.Scheme2
% Do different stuff with varargin
case MyScheme.Scheme3
% Do yet something else with varargin
otherwise
err('Not a valid scheme');
end
end
end
end
However, no matter what scheme I pass in to the constructor, it just goes
straight into the first case. When I add a breakpoint and step through and
manually check equality (scheme == MyScheme.Scheme1), it recognizes that
the two are not equal and returns 0 for this check, so I do not understand
at all why it would still enter first case. If I change the order of the
cases it will just enter whichever one is first. As far as I can tell,
this is identical syntax to the Using Enumerations in a Switch Statement
section of this MATLAB help document, but perhaps I am missing something
obvious?
