Because MATLAB applies scalar expansion to satisfy the size restriction, the following

assignment does not trigger the PreSet or PostSet events.

obj = AbortTheSet;

obj.PropOne = 7;

get.PropOne called

obj.PropOne

Pre-get event triggered

get.PropOne called

Post-get event triggered

ans =

7 7 7
