Hello.
I have a raw data in array.
My question is how to implement the second order backward-difference scheme using the second order forward-difference scheme at the appropriate end points.
I never heard of this.
Please, help.

  What kind of quantity is it you are approximating with the differencing you describe: an integral, a derivative, a second derivative?
