Lagrange & Newton interpolation
flurry.dg.fmph.uniba.skLagrange & Newton interpolation In this section, we shall study the polynomial interpolation in the form of Lagrange and Newton. Given a se-quence of (n +1) data points and a function f, the aim is to determine an n-th degree polynomial which interpol-ates f at these points. We shall resort to the notion of divided differences.

Left-to-right ordering is not necessarily the best! Two better ideas are to order the points in increasing distance from their mean or from a speci ed point at which the interpolant will be evaluated. 12
