[math-fun] Taylor series "inverter"?
Is there a machine out there, analogous to Plouffe's Inverter ( http://pi.lacim.uqam.ca/eng/ ), or the sequences database ( http://www.research.att.com/~njas/sequences/ ), that can take the first n coefficients of a Taylor series and find a function close to that Taylor series? Better yet (of course) take *any* expression for a function and return the simplest expression of the function based on well- known functions. --Steve p.s. I am behind in my egg-collecting.
Hello, Yes, there is a package in Maple that does that : GFUN and it is distributed within the standard Maple. Just type ?gfun in Maple. For a quick answer, try ?guessgf in a Maple session. I believe there is also an equivalent program in Mathematica as well. Simon Plouffe

Martin Rubey recently wrote a program in Axiom that (he claims) is better, see http://front.math.ucdavis.edu:80/math.CO/0702086 Alec Mihailovs http://mihailovs.com/Alec/
