MINIMIZING ROUND-OFF ERROR IN DIRECT SOLUTION OF LARGE SPARSE SYSTEMS OF LINEAR EQUATIONS

Research output: Contribution to journalMeeting Abstractpeer-review

Abstract

The round-off error propagation associated with the use of Shacham and Kehat's direct method for the solution of large sparse systems of linear equations is investigated. A reordering scheme for reducing error propagation is proposed as well as a method for iterative refinement of the solution. Accurate solutions for linear systems, which contain up to 500 equations, have been obtained using the proposed method, in very short computer times.
