Re: [Math] EigenDecompositionImpl#getEigenvector()

Numerical issues should not impinge on a computation this small. For reference, I replicated your computation and found reasonable eigenvalues and vectors: > m = matrix(c(0,1,-1,1,1,0,-1,0,1), nrow=3) > m [,1] [,2] [,3] [1,]01 -1 [2,]110 [3,] -101 > eig(m) Err

[Math] EigenDecompositionImpl#getEigenvector()

Hello I'm trying to calculate the Eigenvectors of this Wikipedia example: http://en.wikipedia.org/wiki/Eigenvalue_algorithm#Identifying_eigenvectors with this JUnit method: public void testEigenDecomposition() { double[][] m = { { 0.0, 1.0, -1.0 }, { 1.0, 1.0, 0.0 }, { -1.0, 0.0, 1.0 } };
