A base class for smoother handling information on smoothing. While not adding to the abstract interface in MGSmootherBase, this class stores information on the number and type of smoothing steps, which in turn can be used by a derived class.

| const bool | variable = false, |
||
| const bool | symmetric = false, |
||
| const bool | transpose = false |
||
| ) |
Constructor. Sets smoothing parameters and creates a private GrowingVectorMemory object to be used to retrieve vectors.

| const unsigned int | steps = 1, |
||
| const bool | variable = false, |
||
| const bool | symmetric = false, |
||
| const bool | transpose = false |
||
| ) |
Constructor. Sets memory and smoothing parameters.
| void MGSmoother< VECTOR >::set_steps | ( | const unsigned | int ) |
Modify the number of smoothing steps on finest level.
| void MGSmoother< VECTOR >::set_variable | ( | const | bool ) |
Switch on/off variable smoothing.
| void MGSmoother< VECTOR >::set_symmetric | ( | const | bool ) |
Switch on/off symmetric smoothing.
| void MGSmoother< VECTOR >::set_transpose | ( | const | bool ) |
Switch on/off transposed smoothing. The effect is overriden by set_symmetric().
| void MGSmoother< VECTOR >::set_debug | ( | const unsigned int | level ) |
GrowingVectorMemory<VECTOR> MGSmoother< VECTOR >::my_memory [private] |
The memory object to be used if none is given to the constructor.
Definition at line 115 of file mg_smoother.h.
unsigned int MGSmoother< VECTOR >::steps [protected] |
Number of smoothing steps on the finest level. If no variable smoothing is chosen, this is the number of steps on all levels.
Definition at line 125 of file mg_smoother.h.
bool MGSmoother< VECTOR >::variable [protected] |
Variable smoothing: double the number of smoothing steps whenever going to the next coarser level
Definition at line 133 of file mg_smoother.h.
bool MGSmoother< VECTOR >::symmetric [protected] |
Symmetric smoothing: in the smoothing iteration, alternate between the relaxation method and its transpose.
Definition at line 141 of file mg_smoother.h.
bool MGSmoother< VECTOR >::transpose [protected] |
Definition at line 150 of file mg_smoother.h.
unsigned int MGSmoother< VECTOR >::debug [protected] |
Output debugging information to deallog if this is nonzero.
Definition at line 157 of file mg_smoother.h.
SmartPointer<VectorMemory<VECTOR>, MGSmoother<VECTOR> > MGSmoother< VECTOR >::mem [protected] |
Memory for auxiliary vectors.
