Set UMFPack-specific options.
This method allows to set various options that control the UMFPack solver. More specifically, it allows to set values in the UMF_Control array. Please see the UMFPack documentation for a list of possible options and values.
- Parameters
-
option | Entry in the UMF_Control array, e.g., UMFPACK_IRSTEP |
value | Corresponding value |

Constructs the SuperLU solver.
During the construction the matrix will be decomposed. That means that in each apply call forward and backward substitutions take place (and no decomposition).
- Parameters
-
mat | The matrix of the system to solve. |
verbose | If true some statistics are printed. |
reusevector | Default value is true. If true the two vectors are allocate in the first call to apply. These get resused in subsequent calls to apply and are deallocated in the destructor. If false these vectors are allocated at the beginning and deallocated at the end of each apply method. This allows using the same instance of superlu from different threads. |
