basic linear algebra computations



(1) The problem you had with the demo is a bug with a pathname.
I'll fix it soon and let you all know when it's fixed.

(2) My code requires nset, and maybe even a fairly new version.
You can get nset from either the maxima CVS or my webpage. I've
forgotten, but I think you are correct that nset isn't in
maxima 5.9.0.  Try load("nset").  If that fails, most likely
you don't have it.

(3) My code requires the emptyp function from nset. It
seems that there is another emptyp function defined
elsewhere in maxima (ick). I'll look into that.

Thanks for the interest.  As time allows, I plan to
add more functions to linalg.mac.  I'm open to suggestions.
