Gfun: a Maple package for solutions of linear differential or recurrence equations

Gfun is a Maple package that provides tools for: guessing a sequence or a series from its first terms; manipulating rigorously solutions of linear differential or recurrence equations, using the equation as a data-structure.

Its development moved to AriC with Bruno Salvy in 2012, while a submodule NumGfun dedicated to symbolic-numeric computations with linear ODEs has been developed by Marc Mezzarobba during his post-doc at AriC. An old version of gfun is distributed with the Maple library. Newer versions are available on the web page of gfun, which also lists a number of articles by scientists who cited it.
