KmlScaissCsiSubPcSet?I?

Set the parameters related to the Block-Jacobi sub-preconditioners in the iterative solution.

C interface:

int KmlScaissCsiSubPcSetSIS(KmlScasolverTask **handle, enum KmlSolverPreconditionerParam param, int subn, const float *data, int nd);

int KmlScaissCsiSubPcSetSII(KmlScasolverTask **handle, enum KmlSolverPreconditionerParam param, int subn, const int *data, int nd);

int KmlScaissCsiSubPcSetDII(KmlScasolverTask **handle, enum KmlSolverPreconditionerParam param, int subn, const int *data, int nd);

int KmlScaissCsiSubPcSetDID(KmlScasolverTask **handle, enum KmlSolverPreconditionerParam param, int subn, const double *data, int nd);

Parameter	Type	Description	Input/Output
handle	KmlScasolverTask **	Solver handle, which is a variable passed from a previous step.	Input/Output
param	enum KmlSolverParam	KML_RELAXATION_FACTOR indicates the parameters related to the SOR preconditioner. KMLSS_DROP_FILL indicates the maximum number of elements to be retained per row for the ILUT preconditioner. KMLSS_DROP_TOL indicates the threshold for retaining elements for the ILUT preconditioner.	Input
subn	int	Index of a sub-preconditioner.	Input
data	const int * in KmlScaissCsiSubPcSetSII/KmlScaissCsiSubPcSetDII const float * in KmlScaissCsiSubPcSetSIS/KmlScaissCsiSubPcSetSLS const double * in KmlScaissCsiSubPcSetDID/KmlScaissCsiSubPcSetDLD	Parameters related to the preconditioner.	Input
nd	int	Number of elements in the data array.	Input

Return Value	Type	Description
KMLSS_NO_ERROR	int	Normal execution.
KMLSS_DATA_SIZE	int	The value of nd is not 1.
KMLSS_NULL_ARGUMENT	int	A null argument exists in {handle, data}.
KMLSS_BAD_SELECTOR	int	param is invalid.
KMLSS_BAD_PRECONDITIONER	int	The selected preconditioner has not been implemented.
