I have a fairly small matrix (cca 100x100). I have computed first four largest eigenvalues (with modified Lanczsos and Lanczsos with reorthogonalization). I know this might be a rather dumb question, but I can't find a way to compute corresponding eigenvector in Matlab. Sure I remember, how to calculate it by hand: Calculate kernel of matrix $(A - \lambda I)$ and you get corresponding eigenvector.
So, is there any "easy" way to get this done in Matlab?
