	And so, ...

	Last week Ron Gallant and I asked about getting LINPACK and
EISPACK in C or C++.  A good bit of mail to me requested a summary.
Ok, here's the response so far. (Sorry about the sci.math.num-analysis
add-on, I forgot to cross-post there at the beginning of all this.  If
anyone there has any information on this, could you send me email?)

        emv@math.lsa.umich.edu suggested getting the index from
netlib@ornl.gov.  Sure enough this showed the LINPACK and EISPACK
fortran routines and one sparse matrix eigenvalue package in C.  But
sadly, no LINPACK and EISPACK in C.

        mikem+@andrew.cmu.edu (and a couple of others) suggested using
f2c on the EISPACK code.  This will likely do it but the code seems
guaranteed to be ugly and unreadable.  This will still get the job
done of course but I (and apparently others) want the same edification
from looking at C code as I used to get from reading f-word code.  This
appears to be the best lead so far but...  Instead of everyone going
off and running f2c over and over, wouldn't it be nice if the same
beautiful LINPACK/ EISPACK style showed up in one set of C source?
