Spline Approximation (Mathematics)

The goal of spline approximation has already been explained in the previous article „Spline Approximation (Introduction)„. This article will cover the mathematics behind this approximation and develop an approach. If you do not care about the mathematics, just skip this article and read the Spline Approximation (Cookbook)“, that will come soon. Spline Interpolation We have …

Spline Approximation (Introduction)

We sometimes encounter a situation where a number of points with coordinates are given and we want to find a function such that for all of these points we have (interpolation) or (approximation). Most often we say that we want on average to be as small as possible and for whatever reasons usually the quadratic …
