Is there a Mathematica package to do geometric algebra calculations?
David Park has developed a geometric (Grassmann) algebra package. Check his community profile. It has a dropbox link from where the package can be downloaded.
Yes, I have it downloaded. But I wanted a package based on Hestenes.
A web search for āgeometric algebra Mathematica packageā turns up several hits. At least one was presented at a Wolfram Technology Conference, author being Terje Vold (I recall it being a good talk but Iāve not used the package).
Eric Lengeyl (Terathon Software) has published a Geometric Algebra package to Github.
