Padé approximants: CRAN package

Published by on June 10, 2015

While working on the previous post about Padé approximants, a search on CRAN showed that there was only one package which calculated the coefficients, given the appropriate Taylor series: the pracma package. The method it uses seems rather sophisticated, but does allow for calculating coefficients “beyond” that which the Taylor series would allow. Therefore, I Read the full article…

A Practical Example of Calculating Padé Approximant Coefficients Using R

Introduction I recently had the opportunity to use Padé approximants. There is a lot of good information available on line on the theory and applications of using Padé approximants, but I had trouble finding a good example explaining just how to calculate the co-efficients. Basic Background Hearken back to undergraduate calculus for a moment. For Read the full article…
