Michael Trosset wrote a program for classical metric MDS that Mark Rorvig
and I used with success on matrices much larger than 400 by 400. But it
doesn't do nonmetric MDS. The program is written in Fortran and requires the
ARPACK libraries. I was able to compile with g77 on Linux  and Solaris with
little trouble.
