double | relaxation |
Permuted SOR preconditioner using matrix built-in function. The MATRIX
class used is required to have functions PSOR(VECTOR&, const VECTOR&, double)
and TPSOR(VECTOR&, const VECTOR&, double)

Initialize matrix and relaxation parameter. The matrix is just stored in the preconditioner object.
The permutation vector is stored as a pointer. Therefore, it has to be assured that the lifetime of the vector exceeds the lifetime of the preconditioner.
The relaxation parameter should be larger than zero and smaller than 2 for numerical reasons. It defaults to 1.
void PreconditionPSOR< MATRIX >::vmult | ( | VECTOR & | , |

) | const |
Apply preconditioner.
void PreconditionPSOR< MATRIX >::Tvmult | ( | VECTOR & | , |
const VECTOR & | |||
) | const |
Apply transpose preconditioner.
