KmlDssSymClean?I

释放内部数据结构，将Handle指向空指针。

接口定义

C Interface：

int KmlDssSymCleanSI(KmlSolverTask **pHandle);

int KmlDssSymCleanDI(KmlSolverTask **pHandle);

int KmlDssSymCleanCI(KmlSolverTask **pHandle);

int KmlDssSymCleanZI(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 = 8;
int ia[9] = {0, 2, 4, 6, 8, 10, 12, 13, 14};
int ja[14] = {0, 2, 1, 3, 2, 4, 3, 5, 4, 6, 5, 7, 6, 7};
double a[14] = {1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0, 13.0, 14.0};
double b[8] = {3.0, 7.0, 13.0, 19.0, 25.0, 31.0, 23.0, 26.0};
double x[8];
KmlSolverTask* matrix_handle = NULL;
int ierr = KmlDssSymInitDI(&matrix_handle, n, a, ja, ia);
if (ierr != 0) {
    printf("\nERROR in KmlDssSymInitDI: %d", ierr);
}
ierr = KmlDssSymAnalyzeDI(&matrix_handle);
if (ierr != 0) {
    printf("\nERROR in KmlDssSymAnalyzeDI: %d", ierr);
}
ierr = KmlDssSymFactorizeDI(&matrix_handle);
if (ierr != 0) {
    printf("\nERROR in KmlDssSymFactorizeDI: %d", ierr);
}
ierr = KmlDssSymSolveDI(&matrix_handle, nrhs, x, ldx, b, ldb);
if (ierr != 0) {
    printf("\nERROR in KmlDssSymSolveDI: %d", ierr);
}
ierr = KmlDssSymCleanDI(&matrix_handle);
if (ierr != 0) {
    printf("\nERROR in KmlDssSymcleanDI: %d", ierr);
}
