A survey of Lanczos procedures for very large real 'symmetric' eigenvalue problems
A description of various variants of the Lanczos method for computing eigenvalues of a symmetric matrix pencil is given. The variants are classified after how much reorthogonalization is used, after whether block or single vector iteration is used and whether several (block) tridiagonal matrices are computed after eachother in an iterative fashion.
