1 2 The basic interpolation problem Consider a set ofn+ 1 points (x; y) (x0; y0); (x1; y1); : : : ; (xn; yn): Thex-values are called theabscissasornodes They-values are assumed to come fromsome underlying functionf i e yi =f(xi); Figure 1: Interpolating polynomial for data at three abscissas (x0; x1; x2) and two possiblefunctionsf(x)
Figure 1: Interpolating polynomial for data at three nodes (x0; x1; x2) and two possiblefunctionsf(x) Given three pointsp(x) may not be a good estimate off(right) - theinterpolant cannot know whatfdoes between the data points 2 Polynomial interpolation (Lagrange) One approach to approximation is calledinterpolation Suppose we have the data
The simplest form of interpolation is probably thestraight line connecting two points by a straight line Let two data points (x0y0)and(x1y1)begiven There is a unique straight line passing through thesepoints We can write the formula for a straight lineas P1(x)=a0+a1x
Interpolation Interpolation is the process of de?ning a function that takes on speci?ed values at speci?ed points This chapter concentrates on two closely related interpolants: the piecewise cubic spline and the shape-preserving piecewise cubic named “pchip ” 3 1 The Interpolating Polynomial
Polynomial Interpolation I Given data x 1 x 2 x n f 1 f 2 f n (think of f i = f(x i)) we want to compute a polynomial p n 1 of degree at most n 1 such that p n 1(x i) = f i; i = 1;:::;n: I A polynomial that satis es these conditions is called interpolating polynomial The points x i are called interpolation points or interpolation nodes
