Let K = cfw_x0, . . . , xm be a set of given knots with
a = x0 < x1 < < xm = b
Denition. [11.2] A function s C 2[a, b] is called a cubic spline on [a, b],
if s is a cubic polynomial si in each interval [xi, xi+1].
It is called a cubi

Recall.
During Wednesdays lecture we saw that each cubic in
the spline interpolant can be written as
si (x) = i (x xi1 ) + i

Spline interpolation
Given a tabulated function fk = f(xk ), k = , . . . N, a spline is a polynomial between each pair of tabulated
points, but one whose coefficients are determined slightly non-locally. The non-locality is designed to
guarantee global
SPLINE INTERPOLATION
Spline Background
Problem: high degree interpolating polynomials often
have extra oscillations.

Splines
Let a = x0 < x1 < . . . < xn1 < xn = b. A spline of degree m is a function
S(x) which satises the following conditions:
1. For x [xi , xi+1 ], S(x) = Si (x): polynomial of degree m
2. S (m1) exists and continuous at the interior points x1 , . . .

Introduction
In the last lecture we saw that linear splines are a cheap way to interpolate our n + 1 points (x 0 , y0 ) to
