GIVENS: An Out-of-Core Eigensystem Subroutine for Large Order Symmetric Matrices.
Abstract
The need to compute eigenvalues and eigenvectors for large order symmetric matrices arises frequently in the finite element approach to static structural analysis as well as in the applied work of many other fields in the Navy's varied research program. GIVENS is an out-of-core FORTRAN callable eigen-system subroutine which computes all the eigenvalues and specified eigenvectors for a large order real symmetric matrix using modifications of the GIVENS tridiagonalization procedure, the QR method of Francis, and inverse iteration.
