wanted: Emacs integrated CLISP env for NT, *AND* mathematics package for CLISP

I was looking for a free implementation of a common lisp environment that

is integrated the the WinNT implemention of emacs

( http://www.*-*-*.com/ ).

I am also looking for a common LISP mathematics package that can find the

eigenvectors and eigenvalues of a rather large matrix.

Thanks much
