public class AlgorithmQuinticLagrangian
extends AlgorithmBase

This is a polynomial p of degree 5 which interpolates a given function f at the points x(-2), x(-1), x(0), x(1), x(2), and x(3) and is given by p(x) = sum from i = -2 to i = 3 of li(x)*f(xi), where li, i = -2,-1,0,1,2,3 which are called the fundamental polynomials, are given by li(x) = product from k = -2 to k = 3 for k != i of (x - xk)/(xi - xk). li(-2) = (x - -1)/(-2 - -1) * (x - 0)/(-2 - 0) * (x-1)/(-2 - 1) * (x-2)/(-2 - 2) * (x-3)/(-2 - 3) = (x * (x*x - 1) * (2 - x) * (x - 3))/120 li(-1) = (x - -2)/(-1 - -2) * (x - 0)/(-1 - 0)* (x-1)/(-1 - 1) * (x - 2)/(-1 - 2) * (x - 3)/(-1 - 3) = (x * (x*x - 4) * (x - 1) * (x - 3))/24 li(0) = (x - -2)/(0 - -2) * (x - -1)/(0 - -1) * (x - 1)/(0 - 1) (x - 2)/(0 - 2) * (x - 3)/(0 - 3) = ((x*x - 4) * (x*x - 1) * (3 - x))/12 li(1) = (x - -2)/(1 - -2) * (x - -1)/(1 - -1) * (x - 0)/(1 - 0) * (x - 2)/(1 - 2) * (x - 3)/(1 - 3) = (x * (x*x - 4) * (x+1) * (x-3))/12 li(2) = (x - -2)/(2 - -2) * (x - -1)/(2 - -1) * (x - 0)/(2 - 0) * (x - 1)/(2 - 1) * (x - 3)/(2 - 3) = (x * (x*x - 1) * (x+2) * (3 - x))/24 li(3) = (x - -2)/(3 - -2) * (x - -1)/(3 - -1) * (x - 0)/(3 - 0) * (x - 1)/(3 - 1) * (x - 2)/(3 - 2) = (x * (x*x - 1) (x*x - 4))/120
