I am trying to calculate the eigenvector when the eigenvalue is zero for a 9x9 matrix. Using 'Eigenvalues' gives me several answers including zero, but also some complex numbers. When I try using 'Eigenvectors' it trys to compute the eigenvectors for all of the eigenvalues. Unfortunatly the it seems that it can not calculate the eigenvectors for the complex numbers and fails to provide an answer (it just runs for hours without any output). Does anybody know how I can calculate just the eigenvector corresponding to the zero eigenvalue? Thanks, Alastair (I'm using Mathematica 3.0 for Win 95) -----== Posted via Deja News, The Leader in Internet Discussion ==----- http://www.dejanews.com/ Now offering spam-free web-based newsreading
