As I understand it, this is on top of a mathematical question. For
example, what criteria will you use to test this? I'm confident I can
find counter examples to the more obvious ones, so unless you have a
clear context I think your procedure will be unreliable.
There are two approaches that spring to mind:
(1) testing derivatives
(2) using an \epsilon grid (for small epsilon)
I've thought about code to test this in the past (with Maple), but failed
to develop anything reliable. I'd be very interested to know what you
think.
