Jack J. Dongarra, C Moler · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1983
This is a two part paper on the software package EISPACK. The first part describes the development and usage of the EISPACK and is intended as an introduction to the package. The second part describes changes made to the package for the current release and how to install the package. EISPACK is a systemized collection of subroutines that compute the eigenvalues and eigenvectors of different classes of matrices.
