Cybernetics and Systems Analysis Aims and scope

Abstract

The properties of a smooth continuous spline approximation are considered. The existence conditions are established and an algorithm is proposed to determine the parameters of such a spline with segments as the sum of a polynomial and an exponent. The errors of approximating a function and its derivative by such a spline with polynomial segments and segments in the form of the sum of a polynomial and an exponent are estimated.
