Detailed Description

Diagonal incomplete LU preconditioned BiCG solver derived from the general preconditioned BiCG solver PBiCG but with the choice of preconditioner pre-selected.

Deprecated:: This solver is present for backward-compatibility and the PBiCG solver should be used instead. (deprecated Apr 2008)
