I don't know if the algorithm is correct, but it's certainly different than the power method, and presented pretty clearly. I think it's gotten me on the right track at least... Thanks. --[[User:Jjdonald|Jjdonald]] ([[User talk:Jjdonald|talk]]) 22:22, 17 December 2007 (UTC)
== Extracting information from tridiagonal matrix ==
So Lanczos gives you a tridiagonal matrix. I think a link would be helpful which explains how to extract low eigenvalues/eigenvectors from this matrix.
