RE: [MO]: Pade-approximation method for iteration of exp(x) - Gottfried - 02/13/2011
Hi folks - just came across the following entry in mathOverflow: answer of John Sidles He gives a short overview of his method; he has also a longer treatize: Pade-method, PDF Unfortunately I've never done anything with Pade-approximation so I cannot say much meaningful about that approach, it would be good if someone else here could comment on this. Hmm - just when I checked for the authors name I notice, that this article was already posted in december (I must have missed this) and only something was currently edited.

You write in the title exp(x)-1, but it is exp, isnt it? Reminds me a bit of the rational approximation approach by Ansus, though I think he used it rather for the superfunction instead of the fractional iterates. RE: [MO]: Pade-approximation method for iteration of exp(x) - Gottfried - 02/14/2011
