KmlDss(Spd/Hpd)Clean?I

释放内部数据结构，将Handle指向空指针。

接口定义

C Interface：

int KmlDssSpdCleanSI(KmlSolverTask **pHandle);

int KmlDssSpdCleanDI(KmlSolverTask **pHandle);

int KmlDssHpdCleanCI(KmlSolverTask **pHandle);

int KmlDssHpdCleanZI(KmlSolverTask **pHandle);

参数

参数名	类型	描述	输入/输出
pHandle	KmlSolverTask **	求解器句柄，传入之前步骤的变量。	输入/输出

返回值

返回值	类型	描述
KMLSS_NO_ERROR	int	正常执行。
KMLSS_NULL_ARGUMENT	int	无效的参数。
KMLSS_BAD_HANDLE	int	pHandle格式存在问题。

依赖

#include "kml_dss.h"或#include "kml_solver.h"

示例

C Interface：

int n = 2;
int ia[3] = {0,2,4};
int ja[4] = {0,1,0,1};
double a[4] = {2,1,1,2};
double b[2] = {3,1};
double x[2];
int nrhs = 1;
int ldx = n, ldb = n;
KmlSolverTask* matrix_handle = NULL;
int ierr = KmlDssSpdInitDI(&matrix_handle, n, a, ja, ia);
if (ierr != 0) {
    printf("\nERROR in KmlDssSpdInitDI: %d", ierr);
}
ierr = KmlDssSpdAnalyzeDI(&matrix_handle);
if (ierr != 0) {
    printf("\nERROR in KmlDssSpdAnalyzeDI: %d", ierr);
}
ierr = KmlDssSpdFactorizeDI(&matrix_handle);
if (ierr != 0) {
    printf("\nERROR in KmlDssSpdFactorizeDI: %d", ierr);
}
ierr = KmlDssSpdSolveDI(&matrix_handle, nrhs, x, ldx, b, ldb);
if (ierr != 0) {
    printf("\nERROR in KmlDssSpdSolveDI: %d", ierr);
}
ierr = KmlDssSpdCleanDI(&matrix_handle);
if (ierr != 0) {
    printf("\nERROR in KmlDssSpdcleanDI: %d", ierr);
}
