Thanks, I already have the Deivy Petrescu matrix libraries. They've
been updated recently and can be found at:

Here are a few helpful elementary matrix functions that might provide
a start.
Several functions are also available in mathematica which may be
accessible depending on your use.
I have reprinted here an old document followed by the scripts that
were sownloaded (ages ago)
I have been unable to find the location that I got them from, but the
website referred to in the ReadMe
still exists and the author, Deivy Petrescu, may be reachable.
I have not tested thes on newer systems (post sys 8.5) (Yeah I
remember when that was new, and Sys 6 too.)
Some of the characters probably will get trashed by the ListServe, so
if anybody wants the original files on this
please contact me directly.
