Preconditioned Conjugate Gradient Schemes

Abstract

The conjugate gradient method is a powerful algorithm to solve well-structured sparse linear systems that arise from partial diierential equations. We consider here three diierent conjugate gradient schemes for solving elliptic partial diierential equations that arise from 5-point diierence schemes: the classical CG, CG with a block diagonal-block… (More)
