Given a cubic spline interpolation: So(x)=1−2x x∧3,0<x<1 Sx =2 ... | Filo

To study the accuracy of cubic spline interpolation, use a package program to construct interpolating splines to y=e^x on 0 ≤x ≤1. Use evenly spaced nodes on [0,1] to generate the data, say, with 10,20 , and 40 subdivisions. Then check the accuracy of the spline function at four times that many points. Do this for (a) the cubic natural interpolating spline function, and (b) the spline satisfying (4.71) or (4.72). Discuss your results. How does the error behave as the number of subdivisions is do

Natural cubic spline:If f is defined at x0, x1, ..., xn-1 and h = xi 1 - xi, then f has a unique natural spline interpolation on the nodes xi. The interpolation function S(x) is given by S(x) = ai bi(x - xi) ci(x - xi)^2 di(x - xi)^3 for i = 0, 1, ..., n-1. To obtain the values of bi and di, use the following formulas:bi = (ai 1 - ai) / h - (ci 1 2ci)h / 3di = (ci 1 - ci) / (3h)To solve the equation Ax = h, where A is a tridiagonal matrix, the values of ci can be obtained using the formu
