|Spot operator: opSpot/qmr||Spot Home Page|
QMR Quasi-Minimal Residual Method. X = qmr(A,B) attempts to solve the square linear system A*X=B via the QMR method. This routine is simply a wrapper to Matlab's own QMR routine, and the argument list variations described in Matlab's QMR documentation are also allowed here. The usage is identical to Matlab's default version, except that the first argument must be a Spot operator.
