Hi Taxman, Thanks for the excellent suggestions - this is next in my queue. Yes, some TeX guidance would be helpful, and I'm going to add some, but its not going to become a full-blown tutorial on installing new TeX packages. That's "out of scope." ;-) texhash, mktexls-r, kpsewhich and some n

Hi A recent calculation I made in Sage (version 3.4) gave me a matrix where each value was out by a decimal less than 10 x e-16 or e-17. I have two questions: 1. Is this a usual rounding error in sage or is there an error in my calculations? I didn't notice anything to do with rounding when I w
