JAMA: Java Matrix Package
JAMA is a basic linear algebra package for Java developed by The MathWorks and the National Institute of Standards and Technology (NIST), and is available from http://math.nist.gov/javanumerics/jama/.
Enlighten's AutoUVs code makes use of several routines based on JAMA routines for eigenvector decomposition: tred2, tql2 and eigen_decomposition. These routines are in the public domain. From http://math.nist.gov/javanumerics/jama/ (accessed 7 May 2013):
