Hi,
I am having trouble getting file path of get methods using "which" function in 2021a. I don't encounter this problem in 2016b.
For example, I have a classX which has a method get.something:
  1. In 2016b : which('classX>get.Something') gives the full path of where classX is located.
  2. However in 2021a : which('classX>get.Something') says that get.Something not found.
I have tried many things but not been able to make it work. I am a relatively new to matlab so any help will be appreciated.

Are you taking into account that using which() to inquire about methods of a class generally does not work until at least one object has been constructed from the class?

Yes. I am only facing this problem with get and set methods. All other methods working fine with "which" function. For example: which('classX>Something') works fine

Hi
MATLAB calls get and set methods when any code accesses the properties.
Property access methods do not appear in the list of class methods returned by the methods command and are not accessible through which command. These are also not included in the meta.class object Methods property. This is documented behavior. If you want to get path, you can use function handles for getters and setters.
mc = ?ClassName;
mp = findobj(mc.PropertyList,'Name',PropertyName’);
fh = mp.GetMethod;
fh is function handle for the get method and it can help you locate the code
