Detailed Description

template<typename MatrixType, typename InverseNumberType = typename MatrixType::value_type, typename VectorType = Vector<double>>
class RelaxationBlockSSOR< MatrixType, InverseNumberType, VectorType >

Symmetric block Gauss-Seidel method with possibly overlapping blocks.

This class implements the step() and Tstep() functions expected by the relaxation concept. They perform a multiplicative Schwarz method on the blocks provided in the block list of AdditionalData in symmetric fashion. Differing from PreconditionBlockSSOR, these blocks may be of varying size, non-contiguous, and overlapping. On the other hand, this class does not implement the preconditioner interface expected by Solver objects.
