Efficient linear algebra routines for symmetric matrices stored in packed form

Authors


Abstract

Quantum chemistry methods require various linear algebra routines for symmetric matrices, for example, diagonalization or Cholesky decomposition for positive matrices. We present a small set of these basic routines that are efficient and minimize memory requirements. © 2002 Wiley Periodicals, Inc. J Comput Chem 23: 306–309, 2002
