An Interactive Display for Approximation by Linear Programming

Abstract

An interactive program with a graphical display has been developed for the approximation of data by means of a linear combination of functions selected by the user. The coefficients of the approximation are determined by linear programming so as to minimize the error in either the L, or Lm norm. Auxiliary conditions such as monotonicity or convexity of the approximation can also be imposed. This interactive system is described (including user instructions) and several examples of its use are given.
