On Deriving the Quasi-Minimal Residual Method
A new derivation of the quasi-minimal residual (QMR) method for the solution of a system of linear equations is presented. This derivation differs from the original one in solving a particular least-squares problem by applying simple recurrences rather than computing a QR decomposition by means of G...

A new derivation of the quasi-minimal residual (QMR) method for the solution of a system of linear equations is presented. This derivation differs from the original one in solving a particular least-squares problem by applying simple recurrences rather than computing a QR decomposition by means of Givens rotations. |
