Has anyone written an EigenSystem class they are will to share? I need something that takes a 3x3 matrix and calculates the eigenvalues and eigenvectors. This is a request based on my failed attempt to write one myself with my crappy linear algebra skills failing me. If no one happens to have one to share, helping me fix the current one would be cool as well.

Thanks.

have you looked at jmat on sourceforge?

http://jmat.sourceforge.net/_index.html

also take a look at the javadoc for AbstractMatrix and eigen****** to see what it might do...

not sure if this is usable, but it is worth a shot

Thanks, jmat led me to JAMA. It has the EigenDecomposition class that looks suprisingly like the class I'm trying to write using David Eberly's method. Hopefully, I'll be able to see what I did wrong.
