Detailed Description

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

Block Jacobi (additive Schwarz) method with possibly overlapping blocks.

This class implements the step() and Tstep() functions expected by the relaxation concept. They perform an additive Schwarz method on the blocks provided in the block list of AdditionalData. Differing from PreconditionBlockJacobi, 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.
