The R2014b release notes say "you should not perform operations that assume or require graphics handles to be numeric values", such as "combine handles with data in numeric arrays"
Unfortunately i have some old code that does exactly that. But i can just convert the object handle to an old fashioned numeric handle by wrapping it with double(). For backward compatibility, this is the easiest thing for me to do. (Changing the array to a cell array would break old saved states of the GUI)
So is there any reason that i shouldn't just convert the object handle to a double? Will this capability be removed soon?
