Piecewise linear approximations of fewest line segments

Dan Wilson

Abstract

Schwerdtfeger has considered the problem of interpolation and curve fitting over a given partition by a sum of continuous sectionally linear functions. He showed how to construct an orthogonal system of these functions over a given partition and how to use this system to obtain an approximation of a given function which is best in the least square sense.
