Jens Axel Søgaard wrote most of the linear algebra functions; he's the high-caliber guy to thank for `matrix-solve'. In case he doesn't pop in here to say it himself, you're very welcome. :) Neil ⊥ On 04/22/2013 01:21 PM, Richard Cleis wrote: Recently I used it for estimating orientation para

Recently I used it for estimating orientation parameters of telescopes. Inputs are the locations of stars, outputs are telescope coordinates, parameters describe the relationship of axes to each other and to the earth. In matrix-solve, MX=B are M : J[transpose]J, where the J matrix is filled wit

Yes, the math library is awesome. Many thanks. Richard, what are you using it for? (if you are liberty to say, of course). -joe On Sat, Apr 20, 2013 at 8:28 PM, Richard Cleis wrote: > Thanks for the math library. I started using some of the linear algebra > functions for my paid programming,

[racket] Thanks for Math

Thanks for the math library. I started using some of the linear algebra functions for my paid programming, and have had zero trouble with any of it. Matrix-solve works like a dream, and the docs are on the mark. I have to wonder what would happen if a program manager were looking over my should
