Further Programs for the Solution of Large Sparse Systems of Linear Equations

Abstract

A package of FORTRAN subroutines is presented for the solution of non-symmetric or symmetric sparse linear systems by triangular decomposition. Two principle aims are (1) to handle matrices which originally fit into primary core storage but do so no longer after decomposition, and (2) to solve a sequence of linear systems all of which have the same sparsity structure by generating--in secondary storage--a record of the decomposition process in the form of an integer array. Some experimental results using the package are included.
