Computing best discrete least-squares approximations by first-degree splines with free knots
Ludwig J. Cromme, Jens Kunath, Andreas Krebs
We present an algorithm to compute best least-squares approximations of discrete real-valued functions by first-degree splines (broken lines) with free knots. We demonstrate that t…

Discrete approximation by first-degree splines with free knots
Ludwig J. Cromme, Jens Kunath
This paper deals with the approximation of discrete real-valued functions by first-degree splines (broken lines) with free knots for arbitrary -norms (.…
