Padé approximants: CRAN package

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 put together a new R package, Pade, which uses the simpler system of linear equations to calculate the coefficients and does not permit calculating coefficients beyond the order of the supplied Taylor series. Any and all feedback is appreciated, as always!
