Notes: Supports left and right preconditioning Many br
See KSPBCGSL for additional stabilization Many br
Unlike the Bi-CG-stab algorithm, this requires one multiplication be the transpose of the operator Many brbefore the iteration starts. Many br
The paper has two errors in the algorithm presented, they are fixed in the code in KSPSolve_IBCGS() Many br
For maximum reduction in the number of global reduction operations, this solver should be used with Many brKSPSetLagNorm(). Many br
This is not supported for complex numbers. Many br
