Also check out the other sections such as Wolfram's own repository MathSource has a lot of useful if narrow notebooks for various applications. ColourMaths package allows you to visually select parts of an expression and manipulate them.An alternate Mathematica shell with a GNU readline input (using python, *nix only).(Now built in as of Mathematica 8 with the -script option.) MASH is Daniel Reeves's excellent Perl script essentially providing scripting support for Mathematica v7. ![]() at the Algorithmic Combinatorics group's software page. In particular, there is Theorema for automated theorem proving, and the multitude of packages for symbolic summation, difference equations, etc. RISC (Research Institute for Symbolic Computation) has a variety of packages for Mathematica (and other languages) available for download.John Brown's GrassmannAlgebra package and book for working with Grassmann and Clifford algebras.Jeremy Michelson's grassmannOps package provides resources for doing algebra and calculus with Grassmann variables and operators that have non trivial commutation relations.David Park's Presentation Package (US$50 - no charge for updates).Its newest version is called SciDraw, and it will be released sometime this year. I use it if not for anything else then for the much, much improved control over frame/axes ticks. LevelScheme is a package that greatly expands Mathematica's capability to produce good looking plots.If you link to books on Amazon with affiliate links please mention it, e.g., by putting your name after the link. Please include a short description or comment on why something is great or what utility it provides. Feel free to contribute anything, even small code snippets (as I did below for a timing routine).Īlso, undocumented and useful features in Mathematica 7 and beyond you found yourself, or dug up from some paper/site are most welcome. I'll edit (and invite anyone else to do so too) this main post to include resources which are focused on general applicability in scientific research and which as many people as possible will find useful. ![]() What kind of external packages / tools / resources do you use with Mathematica? ![]() We all know that Mathematica is great, but it also often lacks critical functionality.
