Regarding the _handle _class, you can see here that it mentions the following about this class: Objects that share references with other objects.

What does this mean?

Thanks.

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
