LINPACK is a collection of Fortran subroutines that analyze and solve linear equations and linear least-squares probles. The package solves linear systems whose matrices are general, banded, symmetric indefinite, symmetric positive definite, triangular, and tridiagonal square. In addition, the package computes the QR and singular value decompositions of rectangular matrices and applies them to least-squares problems. LINPACK uses column-oriented algorithms to increase efficiency by preserving locality of reference. LINPACK was designed for supercomputers in use in the 1970s and early 1980s. LINPACK has been largely superceded by LAPACK which has been designed to run efficiently on shared-memory, vector supercomputers. Developed by Jack Dongarra, Jim Bunch, Cleve Moler and Pete Stewart. 1 Feb 84 If you are interested in acquiring the entire LINPACK, it may make more sense to talk with NAG. NAG distribute the software on a mag tape for a nominal charge. NAG 1400 Opus Place, Suite 200 Downers Grove, IL 60515-5702 708-971-2337, FAX 971-2706
