  +--gov.sns.tools.math.r3.R3x3EigenDecomposition

public class R3x3EigenDecomposition

extends java.lang.Object

Encapsulates the results of an eigenvalue decomposition operation on a R3x3 matrix object. If the matrix is symmetric it can be decomposed as A = R*D*R' where A is this matrix, R is an (special) orthogonal matrix in SO(3), and D is the diagonal matrix of eigenvales of A. Essentially just a wrapper over Jama presenting a consistent interface in case Jama get removed in the future.

Method Summary

R3x3	getConjugationFactor() Get the conjugation matrix for the decomposition.
double[]	getImagEigenvalues() Get the imaginary parts of the eigenvalues.
double[]	getRealEigenvalues() Get the real part of the eigenvalues.
