◆ bslv_info()
| void bslv_info | ( | bslv_memory * | mem, |
| int | count | ||
| ) |
Display convergence information.
- Parameters
-
mem Pointer to solver memory object. count Number of linear iterations (returned by linear solver)
◆ bslv_init()
| void bslv_init | ( | bslv_memory * | mem, |
| double | tol, | ||
| int | max_iter, | ||
| bsr_matrix const * | A, | ||
| bool | use_dilu | ||
