Improvements to the Algorithm that Uses Divided Differences to Determine the Coefficients in B-Spline Interpolation

Liliana Mâtiu-Iovan

Abstract

In numerical measuring processes the interpolation is an important part. Some algorithms of B-spline interpolation were developed along the time. Here are presented two additional methods to reduce the interpolation errors. These methods could be used in any case for uniformly spaced data. These interpolation processes requires supplementary numerical calculations. Always is to choose between a smallest amount of computation and better results of interpolation.
