I'm assuming you know the math involved. If not, I'd be happy to help 
with that off-line directly. Here's a very simple full-Lua linear 
algebra package that I use for just that sort of thing:

-doug@amdad-~/tmp- wget -q http://www.dkrogers.com/lua/LA.zip
-doug@amdad-~/tmp- unzip LA.zip
Archive:  LA.zip
  inflating: LA.lua
  inflating: LA_test.lua
-doug@amdad-~/tmp- lua LA_test.lua
Vector ok
Matrix ok
-doug@amdad-~/tmp-
