Hi,

Is there a possibility in mathematica to get the coefficients or
formula for approximation of spatial derivatives with finite
differences. And, to get these formulas also for different orders of
approximation?

Specifically the function UFDWeights gives the coefficients for the 1D
case,

I need the same for the 2D case: partial derivatives:

f_x, f_y, f_xy,f_xx,_fyy



Thank you
