F I L T L A N :   Filtered Lanczos Eigensolver  


This version dated : Mon May 7 08:13:13 CDT 2012

FILTLAN is a software library written in C/C++ for computing extreme or interior eigenvalues of a symmetric matrix by a polynomial filtered Lanczos procedure. The code for extreme eigenvalues by a standard Lanczos procedure without restarting is also included. In both cases, partial reorthogonalization is provided to improve efficiency.
The code was primarily written by Haw-ren Fang - a post-doctoral associate in Yousef Saad's group. The technical reports listed below provide details on the techniques used in the package. Online documentation will be available soon.
