Block SSOR preconditioning. This class satisfies the relaxation concept.
The functions vmult
and Tvmult
execute a block-SSOR step, based on the implementation in PreconditionBlockSOR. This class requires storage of the diagonal blocks and their inverses.
See PreconditionBlock for requirements on the matrix. The blocks used in this class must be contiguous and non-overlapping. An overlapping Schwarz relaxation method can be found in RelaxationBlockSSOR; that class does not offer preconditioning, though.
<float> and <double>
; others can be generated in application programs (see the section on Template instantiations in the manual).Definition at line 824 of file precondition_block.h.
