Hello Adithya.

With regard to your specific question, I did a search on cpan for
'eigen'<http://search.cpan.org/search?query=eigen&mode=all>and only
found a handful of modules, none of which specifically mentioned
the eigen template library you mention in your post.  So, it looks like
eigen has not (yet?) been worked into Perl, or PDL.  If a developer is
working on this, I have not heard of it.

That having been said, PDL should have all the basic matrix manipulations
that you'll need, and if it doesn't then that needs to be fixed.  What
manipulations were you looking for, specifically?

For what it's worth, I once did a C++ project computing the eigenvalues of a
10,000 x 10,000 matrix using the TNT
package<http://math.nist.gov/tnt/overview.html>.
If you go the route of using plain old C(++), that's another library to
consider.
