Hi,
In a script, I was checking the existence of a plot handle to either make a new plot or to change the x/y data. Surprisingly this didn't work by initially setting the plot handle to []. Reason:
>> ishandle( [] )
ans =
[]
which sort of makes sense.
However, my next step was to initialise the plot handle to 0, which also didn't work, and this was the real surprise:
Even though
Does anybody why zero would be a valid graphics or Java object handle?
Thanks,
Temu
