Interpolation is the process of de?ning a function that takes on speci?ed values atspeci?ed points This chapter concentrates on two closely related interpolants: thepiecewise cubic spline and the shape-preserving piecewise cubic named “pchip ” 3 1 The Interpolating Polynomial We all know that two points determine a straight line
Interpolationis the process of de ning a function thatconnects the dots" between speci ed (data) points In this chapter we focus on two closely relatedinterpolants thecubic splineand theshape-preservingcubic splinecalled pchip" Two distinct points uniquely determine a straight line
Lagrange form of the interpolating polynomial using MATLAB Refer to the code below for a very naive O(n3) implementation For a more e cient implementation please refer to the barycentric interpolation method discussed in lecture Our results are plotted in Figure 4 1 n= 50; 2 N= 1001; 4
