This is a blocked Lanczos method package.
The LASO package is a set of FORTRAN IV subroutines for computing a few eigenvalues of a large (sparse) symmetric matrix. DILASO Finds all the eigenvalues and eigenvectors of a large sparse symmetric matrix outside a user defined excluded interval. DNLASO Finds a few eigenvalues and eigenvectors at either end of the spectrum of a large sparse symmetric matrix. (For single precision versions request SILASO and SNLASO) |
