The Eigensystem Capability of Four Subroutine Libraries Available at DTNSRDC.

摘要

The need to compute eigenvalues and eigenvectors arises frequently in applied work in the Navy's varied research program. For a given eigensystem problem several algorithms (methods) may be considered and for a given algorithm several Fortran subroutine implementations may be available to choose from. This report offers help in choosing among the options available at DTNSRDC for the solution of eigensystem problems.
