The Matrix classes that I was working on have run up against some very
difficult intrinsic performance problems that I am trying to solve via
some work on otherwise unrelated tools and compilation strategies.
(Some of these were hinted at in some of my comp.lang.c++ postings
this summer.) In the meantime, Tom Keffer
(keffer@blake.acs.washington.edu), Stephen Pope (scp@sfi.santafe.edu),
and Robert Davies (SRWMRBD@wnv.dsir.govt.nz) all have or will have
some very good, but less general (an asset!) and/or differently
structured freely available Matrix packages. Check them out.  Someday,
a libg++ Matrix package will be available, but I refuse to release the
current classes, partly because they are in disarray, but mostly
because I believe that they are unsuitable for serious heavy-duty
computation. Stay tuned for news on other fronts that will hopefully
alleviate such problems.
