# KSPBICG

Implements the Biconjugate gradient method (similar to running the conjugate gradient on the normal equations).

### Options Database Keys

see KSPSolve() - Many br Many br

Notes: this method requires that one be apply to apply the transpose of the preconditioner and operator Many bras well as the operator and preconditioner. Many brSupports only left preconditioning Many br

See KSPCGNE for code that EXACTLY runs the preconditioned conjugate gradient method on the Many brnormal equations Many br
