| Feb 17, 2012 at 3:08 | comment | added | Kirk S. | @rcompton Absolutely! Here is a reference by Ronald Morgan that may be a good starting point: Computing interior eigenvalues of large matrices. Linear Algebra Appl. 154/156 (1991), 289–309. | |

| Feb 16, 2012 at 6:48 | comment | added | Kirk S. | @rcompton, just to be clear, I am not talking about regular Ritz vectors. I am talking about harmonic Ritz vectors which yield approximations to eigenvectors associated to eigenvalues near the origin (the so-called interior eigenvalues). | |
| Feb 13, 2012 at 18:05 | comment | added | dranxo | Yes Ritz vectors should improve over the Lanczos method. I suppose if the Lanczos idea can work then this will work better. | |
