Lagrange interpolation principle: If y = f (x) takes. y0, y1,…, yn . corresponding to x = x0, x1,…, xn, This method is preferred over its counterparts, such as Newton's method, because it also applicable for unequal spacing of x. Example 1: Program for Lagrange interpolation method Python Code: from math import * def lagrange_interpolation(x,y,u):

Specifically, it gives a constructive proof of the theorem below. This theorem can be viewed as a generalization of the well-known fact that two points uniquely determine a straight line, three points uniquely determine the graph of a quadratic polynomial, four points uniquely 2009-12-08 A kernel-independent treecode (KITC) is presented for fast summation of particle interactions. The method employs barycentric Lagrange interpolation at Chebyshev points to approximate well-separated particle-cluster interactions. The KITC requires only kernel evaluations, is … However, you probably should consider using polynomial interpolation if this is still steppy, please note the theory link, it shows that linear interpolation produces steppy waves. So, the first link I gave, where I grabbed this code from, also has a polynomial algorithm: 2016-04-28 interpolation kernels such as the Kaiser-Bessel function.

Barycentric interpolation is a variant of Lagrange polynomial interpolation that is fast and stable. It deserves to be known as the standard method of polynomial interpolation.

Python code. from math import *. def lagrange_interpolation (x,y,u): r = range(len(y)) a = [y [i]/product (x [i]-x [j]for j in r if j!=i)for i in r] return sum(a [i]*product ( [u-x [j]for j in r if j!=i])for i in r) def product (a): p = 1. for i in a:p*=i.

Mathematically speaking, the Lagrange interpolation will return exactly the same polynomial as the direct definition (in fact all polynomial interpolation methods will give essentially the same polynomial); the form is different though, because Lagrange interpolation avoids solving the linear system for the unknown polynomial coefficients. Lagrange interpolation polynomials are defined outside the area of interpolation, that is outside of the interval [x1, xn], will grow very fast and unbounded outside this region. This is not a desirable feature because in general, this is not the behavior of the underlying data. is known as Lagrange Interpolation Formula for unequal intervals and is very simple to implement on computer.
