KmlScadssGENSet?I?

设置与handle关联的值。

接口定义

C Interface：

int KmlScadssGenSetSII(KmlScaSolverTask **pHandle, enum KML_SOLVER_PARAM param, int *value, int nvalue);

int KmlScadssGenSetDII(KmlScaSolverTask **pHandle, enum KML_SOLVER_PARAM param, int *value, int nvalue);

int KmlScadssGenSetCII(KmlScaSolverTask **pHandle, enum KML_SOLVER_PARAM param, int *value, int nvalue);

int KmlScadssGenSetZII(KmlScaSolverTask **pHandle, enum KML_SOLVER_PARAM param, int *value, int nvalue);

int KmlScadssGenSetDID(KmlScaSolverTask **pHandle, enum KML_SOLVER_PARAM param, double *value, int nvalue);

int KmlScadssGenSetZID(KmlScaSolverTask **pHandle, enum KML_SOLVER_PARAM param, double *value, int nvalue);

int KmlScadssGenSetSIS(KmlScaSolverTask **pHandle, enum KML_SOLVER_PARAM param, float *value, int nvalue);

int KmlScadssGenSetCIS(KmlScaSolverTask **pHandle, enum KML_SOLVER_PARAM param, float *value, int nvalue);

参数

参数名	类型	描述	输入/输出
pHandle	KmlScaSolverTask	求解器句柄，pHandle不可为空指针。	输入
param	enum KML_SOLVER_PARAM	KMLSS_REFINEMENT_MAX_STEPS表示REFINEMENT的最大次数。 KMLSS_PERM表示矩阵行列顺序，暂不支持。 KMLSS_ITER_REF_STEPS表示迭代优化次数，暂不支持。	输入
value	int	直接求解相关参数数组。	输出
nvalue	int	value数组元素个数。	输入

返回值

返回值	类型	描述
KMLSS_NO_ERROR	int	正常执行。
KMLSS_NULL_ARGUMENT	int	pHandle为空指针。
KMLSS_BAD_HANDLE	int	pHandle内部格式转换错误。
KMLSS_BAD_DATA_SIZE	int	KMLSS_FILL_IN数组长度nvalue设置错误。
KMLSS_INTERNAL_ERROR	int	内部数据返回空指针，KMLSS_FILL_IN获取失败。
KMLSS_BAD_SELECTOR	int	用户的KML_SOLVER_PARAM输入当前不支持，或在求解过程中不存在。

示例

C Interface：

MPI_Init(NULL, NULL);
int size, rank;
MPI_Comm_size(MPI_COMM_WORLD, &size);//获取总进程数
MPI_Comm_rank(MPI_COMM_WORLD, &rank);//获取当前进程标识

int n = 8;
int ia[9] = {0, 3, 7, 9, 11, 13, 15, 16, 17};
int ja[17] = {0, 3, 4, 1, 2, 3, 5, 2, 7, 3, 6, 4, 5, 5, 7, 6, 7};
double a[17] = {1.0, 1.0, 2.0, 9.0, 2.0, 1.0, -3.0, 3.0, 2.0, 9.0, -5.0, 6.0, 1.0, 4.0, 1.0, 7.0, 2.0};
double b[8] = {4.0, 9.0, 7.0, 6.0, 9.0, 3.0, 2.0, 5.0};
double x[8];
KmlScasolverTask* matrix_handle = NULL;
int ierr = KmlScadssGenInitDI(&matrix_handle, n, a, ja, ia, MPI_COMM_WORLD);
ierr = KmlScadssGenSetDII(&matrix_handle, KMLSS_REFINEMENT_MAX_STEPS, &max_refinement_steps , 1);
ierr = KmlScadssGenAnalyzeDI(&matrix_handle);
ierr = KmlScadssGenFactorizeDI(&matrix_handle);
int nrhs = 1;
int ldx=n, ldb=n;
