Arioli M., Manzini G. The MI27 Package Implementation. Technical report ercim.cnr.ian//2002-1313, 2002.
 
 
Abstract
(English)
In this report, we describe the implementation of the routine MI27 for the Harwell Subroutine Library collection. The routine implements the conjugate gradient method by using the reverse communication technique, and allows the user to select the stopping criterion among several ones based on Gauss and Gauss-Radau error estimates.
Subject Linear Algebra Systems, Sparse Matrix, Conjugate Gradient Method, Error Estimators, Stopping Criteria
