[David Arnold]

Hans,

Just got a numerical linear algebra activity up at:

merical-s.pdf

and

http://online.redwoods.cc.ca.us/instruct/darnold/LINALG/numerical/context-nu
merical-p.pdf

They look pretty nice, thanks to Context.

By the way, there was some discussion of a repository for Context stuff
people are doing. Did that ever get off the ground?
