I meant:

From dx compute the first row of the array (one dim_x vector).
Use dy to go from the first to the second row.
and so on.

But I do realize that this approach is not the best one if you
have experimental data and the divergence of (dx,dy)
is not zero.

But you haven't really described how you got dX and dY and
what is the potential....

Ciao,
