Approximating functions by means of symbolic computation and a general extrapolation method

Abstract
Using a general extrapolation algorithm we present MAPLE procedures for the generation of polynomial and rational approximations to functions having formal series expansions. This algorithm, which has been called E algorithm or Brezinski-Håvie (BH) protocol, includes most of the series (sequence) transformations actually known. MAPLE's ability to perform all calculations in rational arithmetic eliminates the numerical instability of the E algorithm. For nume...

Nature of problem
Approximating functions by means of formal series expansions is a technique which is applied quite frequently in the mathematical treatment of physical problems. To improve the quality of the approximation by appropriate extrapolation methods is highly desired.
