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.

urrks. True - seems my brain lowers its input-separation precision... :-(
I'll update the header line. Thanks for the check
