Application of Rational Function Approximations to Polynomial Functions

摘要

This study deals, with approximating polynomial function using rational functions. This situation arises in experimental measured dependencies, which is useful in non-linear analogue function block designs and the approximation of inverse functions. The dependencies are usually given in analytical form or measured data form. We examine these dependencies in this study and show the application with a simple example. The results showed that rational function method is a more general method of approximation than the polynomial functions.
