Forward finite divided difference
Did you know?
WebFinite difference equations enable you to take derivatives of any order at any point using any given sufficiently-large selection of points. By inputting the locations of your sampled points below, you will generate a finite difference equation which will approximate the derivative at any desired location. ... Notable cases include the forward ... In mathematics, divided differences is an algorithm, historically used for computing tables of logarithms and trigonometric functions. Charles Babbage's difference engine, an early mechanical calculator, was designed to use this algorithm in its operation. Divided differences is a recursive division process. Given a sequence of data points , the method calculates the coefficients of the interpolation polynomial of these points in the Newton form.

Simply shifting your index by 1 can solve it. You'll just need to remember that now your d (1) is the old d (0) ( or say, the d (0) you see in math text). The math remains the same, you just index them differently. n = 15; t = -5:5; d = zeros (1,n+1); % Give d one more element. schedule an omicron booster
