type TMKL_Sparse_sor_type = ( SPARSE_SOR_FORWARD = 110, SPARSE_SOR_BACKWARD = 111, SPARSE_SOR_SYMMETRIC = 112 );
Applies to SOR interface; define type of (S)SOR operation to perform
Values
| Name | Description |
|---|---|
| SPARSE_SOR_BACKWARD | (omegaU + D)*x^1 = (D - omega*D - omega*L)*alpha*x^0 + omega*b |
| SPARSE_SOR_FORWARD | (omegaL + D)*x^1 = (D - omega*D - omega*U)*alpha*x^0 + omega*b |
| SPARSE_SOR_SYMMETRIC | SSOR, for e.g. with (omega == 1) and (alpha == 1), equal to solving a system: (L + D) X x^1 = b - U*x; (U + D) X x = b - L*x^1 |
