This portable, modular Fortran 90 software package implements the thick-restart
|
|
Lanczos method, for use with real symmetric or complex Hermitian eigenvalue
|
|
problems where a small number of eigevalues and eigenvectors are needed, and
|
|
the matrices involved may be too large to store in computer memory. Most of
|
|
the arithmetic computations in the software are done through calls to BLAS
|
|
and LAPACK. The software can be instructed to write checkpoint files so that
|
|
it can be restarted is a later time.
