It means that when you make a change to 1 handle object, any copies of it will feel the same change. So for example, suppose I had
classdef myclass<handle
properties
p;
end
end
Then I would get behavior like this:
>> handle1=myclass; handle2=handle1;
>> handle1.p=5; handle2.p
ans =
5
>> handle1.p=7; handle2.p
ans =
7
