Hi all,

I have a potential field on a grid (it has periodic boundary
conditions), and I want to calculate the acceleration (force field) of
this, i.e., f=-grad(potential), I need the gradient of the potential .
I wrote a procedure, but it has to many for loops in it. Does any body
know a fast and smart way to do this?
Thanks!!

Andres
