when "clear all" does not clear all?

Hello. Sometimes I have a problem with modifying a class file. After I modify the file containing a class description, I run >> clear all The workspace becomes empty, I do not see any Matlab objects anywhere. However, when I try to instantiate the class, I sometimes (with annoying frequency) get a message that the class file had been modified and modifications will not take effect until I clear all objects of this class. Since I see not objects in the workspace, I do not know what to clear. I repeat "clear all" many times with no effect. Usually in this case I have to exit from Matlab and start it again. This is inconvenient, to say the least.
The class does not have static or constant properties. Or global properties, for that matter. Or persistent.
Any ideas would be greatly appreciated.
Thank you,
N. Derzhi

Hello Naum, You might want to try 'clear classes'. See 'help clear' for information.

I faced similar issue, where after editing the class, I was initializing object of older calss. Running following commands helped me with the issue
clear classes
clear pcode
rehash path
rehash toolboxcache

One potential reason why you may be unable to clear a class is if an instance is stored in a property in a figure window, potentially inside an anonymous function.
obj = myClass;
f = figure;
f.UserData = obj;
clear all % obj and f are deleted, but the figure remains open
clear classes % the instance inside the figure UserData prevents myClass from being cleared
