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.
