WebIn science and engineering applications it is often the case that an exact formula for f(x) is not known. We may only have a set of data points (x 1,y 1), (x 2,y 2),...,(x n,y n) available to describe the functional dependence y = f(x). If we need to estimate the rate of change of y with respect to x in such a situation, WebApr 11, 2012 · Differences for points near the edges are calculated with lower order. For example, if n=5 and length (f)=10, then 3-point central differencing is used to calculate values at points 2 and 9, 2-point forward differencing is used for point 1, 2-point backward differencing is used for point 10, and 5-point central differencing is used for points 3-7.
