title: Java package for eigenvector/eigenvalues computation?
body: <p>which java package do you recommend for computing eigenvectors/eigenvalues? I know about <a href="http://jmathtools.berlios.de/doku.php" rel="nofollow noreferrer">JMathTools</a> and <a href="http://math.nist.gov/javanumerics/jama/" rel="nofollow noreferrer">JAMA</a>; do you have some pro/cons for these packages? Other suggestions?</p>
