25 Class

28 Description
29     Incomplete Cholesky preconditioned CG solver derived from the general
30     preconditioned CG solver PCG but with the choice of preconditioner
31     pre-selected.
33 Deprecated
34     This solver is present for backward-compatibility and the PCG solver
35     should be used for preference.
