409. NICER: Nagoya Iterative Computation Eigen Routines
by Yoshitaka Beppu, Department of Physics, and Ichizo Ninomiya, Department of Information Science, Nagoya University, Nagoya, Japan The program is designed to solve standard and generalized eigenproblems for dense real-symmetric matrices. This system is superior in speed to either EISPACK or other comparable QCPE routines. Efficient algorithms account for the advantage. This advantage should be especially noteworthy in semi-empirical systems. FORTRAN IV (ANSI) Lines of Code: 1600 Recommended Citation: Y. Beppu and I. Ninomiya, QCPE 13, 409 (1981). |
