Some Design Features of a Sparse Matrix Code

Abstract

In the hght of practical experience with HarweU subroutine MA18 for solwng sparse sets of hnear equations by Gaussian elunmation and the growth of knowledge in data structure mampulatmn, we make some comments on techmques which can be usefully employed in such a code Most of these suggestmns have been incorporated m the new HarweU sparse matrix package MA28.
