Constructor. Block size must be given since there is no reasonable default parameter.
double PreconditionBlock< MatrixType, inverse_type >::AdditionalData::relaxation |
Relaxation parameter.
Definition at line 122 of file precondition_block.h.
size_type PreconditionBlock< MatrixType, inverse_type >::AdditionalData::block_size |
Block size.
Definition at line 127 of file precondition_block.h.
bool PreconditionBlock< MatrixType, inverse_type >::AdditionalData::invert_diagonal |
Invert diagonal during initialization.
Definition at line 132 of file precondition_block.h.
bool PreconditionBlock< MatrixType, inverse_type >::AdditionalData::same_diagonal |
Assume all diagonal blocks are equal to save memory.
Definition at line 137 of file precondition_block.h.
PreconditionBlockBase<inverse_type>::Inversion PreconditionBlock< MatrixType, inverse_type >::AdditionalData::inversion |
Choose the inversion method for the blocks.
Definition at line 141 of file precondition_block.h.
double PreconditionBlock< MatrixType, inverse_type >::AdditionalData::threshold |
The if inversion is SVD, the threshold below which a singular value will be considered zero and thus not inverted. This parameter is used in the call to LAPACKFullMatrix::compute_inverse_svd().
