X= % inputting values of xįx= % inputting values of y Forward Interpolation using MATLAB: %Newton’s Forward Difference Formula MATLAB Program

Here are two different MATLAB codes for Newton’s forward as well as backward interpolation, written on the basis of aforementioned derivation cum formula. Which is called Newton’s Backward Difference Formula. x0 are equally spaced and x = x k + sh and x i = x k– ( k –i)h for i = 0, 1. The Newton’s Polynomial can be expresses as: If the nodes are recorded from backward as x k, x k-1. Which is called Newton’s forward difference formula. k- 1 and x = x 0 + shĪgain, the difference x – xi is written as ( s – i )h.įinally, the above expression for Newton polynomial above becomes: This form of Newton’s polynomial can be simplified by arranging x o, x 1, x 2, … x k in consecutively equal space.įor simplicity, use the notation h = x i+1 – x i Now, Newton’s interpolation or polynomial can be expressed as: Where, is the notation of divided difference. Similarly, the coefficients are defined as: The given interpolation of polynomial in Newton’s form can be expressed in linear combination of Newton basis polynomial as follows:Īgain, the Newton basis Polynomials can be defined as: Let us consider a set of k+1 data points (x 0, y 0), (x 1, y 1), (x 2, y 2). You can also check out our earlier tutorials where we discussed C programs for Newton’s forward interpolation and Newton’s divided difference. In this tutorial, we’re going to write Matlab programs for Newton’s forward interpolation as well as Newton’s backward interpolation, going through the mathematical derivation of the interpolation technique in general. Newton polynomial interpolation consists of Newton’s forward difference formula and Newton’s backward difference formula. Here, the coefficients of polynomials are calculated by using divided difference, so this method of interpolation is also known as Newton’s divided difference interpolation polynomial.

Named after Sir Isaac Newton, Newton’s Interpolation is a popular polynomial interpolating technique of numerical analysis and mathematics.
