Raul, Thank you so much! Please tell me this wasn't from a Google, because I didn't find this gem. I also never looked at this section of rosettacode.org before.
Yes, it appears to be about what I asked; I need to really look over the discussion and code. My interest is in recreating in J code similar to the GA Sandbox code from the 2007 book, "Geometric Algebra for Computer Science". http://www.geometricalgebra.net/sandbox.html I have been struggling to teach myself GA for years for physics. I haven't touched Hestenes Geometric Calculus yet. In the meantime, I figured it might help my understanding of GA and J too, to code a bit of GA here and there. I always get the math better when I need to code it. Thanks again.
