Hi,
interesting observation. I would explain as follows: the handle property means, that we use references to objects instead of the objects themselves. This means, that you can manipulate object properties without the need to return the changed object.
The structure of the object itself is not falling into this handle behavior. So you need to return the (new) object.
function obj = add(obj)
N=length(obj)+1;
obj(end+1,1)=TestAdd;
obj(N,1).val=N;
end
Now you call as follows:
>> o = TestAdd(5)
o =
5x1 TestAdd array with properties:
val
>> o = o.add
o =
6x1 TestAdd array with properties:
val
Of course you can encapsulate this into a new class if you like :).
Hope this helps,
Titus
