Public Member Functions | |
| BaseBlockJacobiPrecond (Table< int > &ablocktable) | |
| the blocktable define the blocks. ATTENTION: entries will be reordered ! | |
| virtual | ~BaseBlockJacobiPrecond () |
| deletes the table | |
| virtual void | GSSmooth (BaseVector &x, const BaseVector &b, int steps=1) const =0 |
| performs steps Gauss-Seidel steps for the equation A x = b | |
| virtual void | GSSmoothPartial (BaseVector &x, const BaseVector &b, BaseVector &y) const |
| performs steps Gauss-Seidel steps for the equation A x = b with partial residual y | |
| virtual void | GSSmoothResiduum (BaseVector &x, const BaseVector &b, BaseVector &res, int steps=1) const =0 |
| does smoothing. The vector res contains the residuum (b-Ax) before and after the smoothing | |
| virtual void | GSSmoothBack (BaseVector &x, const BaseVector &b, int steps=1) const =0 |
| does smoothing in reversed order | |
