KmlIssGcrSet?I?

Set parameters related to iterative solution.

Interface Definition

C interface:

int KmlIssGcrSetSII(KmlSolverTask **handle, enum KML_SOLVER_PARAM param, const int *data, int nd);

int KmlIssGcrSetDII(KmlSolverTask **handle, enum KML_SOLVER_PARAM param, const int *data, int nd);

int KmlIssGcrSetSIS(KmlSolverTask **handle, enum KML_SOLVER_PARAM param, const float *data, int nd);

int KmlIssGcrSetDID(KmlSolverTask **handle, enum KML_SOLVER_PARAM param, const double *data, int nd);

Parameters

Parameter	Type	Description	Input/Output
handle	KmlSolverTask **	Solver handle, which is a variable transferred previously	Input/Output
param	enum KML_SOLVER_PARAM	THRESHOLD indicates the iteration residual threshold. MAX_ITERATIONS_COUNT indicates the maximum number of iterations. RESTART_PARAM indicates the number of vectors to be cleared before the next iteration.	Input
data	const int * in KmlIssGcrSetSII const int * in KmlIssGcrSetDII const float * in KmlIssGcrSetSIS const double * in KmlIssGcrSetDID	Iterative solution-related parameter array (for example, maximum number of iterations)	Input
nd	int	Size of the data array	Input

Return Values

Return Value	Type	Description
NO_ERROR	int	The execution is successful.
DATA_SIZE_ERROR	int	The number of data records is incorrect.
KML_SOLVER_INVALID_ARGUMENT	int	Invalid parameter.
