SOLUTION OF SPARSE LINEAR EQUATIONS USING CHOLESKY FACTORS OF AUGMENTED SYSTEMS
sparse linear equations direct methods unsymmetric matrices
2015/7/3
Cholesky factorizations have reached a high peak of e±ciency for solving sparse
symmetric systems, largely because their Analyze and Factor phases do not con°ict. We explore the
possibility of using...
SOLUTION OF SPARSE RECTANGULAR SYSTEMS USING LSQR AND CRAIG
Conjugate-gradient method least squares regularization
2015/7/3
Various methods for symmetric and unsymmetric systems are reviewed to illustrate
the parallels . We see that the extension of Craig's method closes a gap in existing
theory. However, LSQR is more ec...
