Abstract

Inherent in the classical approach to function approximation are the limitations placed on the scope of choice for functions of approximation. In this paper a novel method that allows us to approximate functions by means of linear combinationsВ of polynomials, trigonometric and exponential functions, polynomials and periodic functions among others, is presented.
This technique uses, on a fixed interval, an initial valueВ linear ordinary differential equation for function approximation and the approximation expressions are obtained in a closed form.
