# KmlScadss(SPD/HPD)Analyze?I

分析数据结构，对稀疏矩阵进行重排和符号分解。

#### 接口定义

C Interface：

int KmlScadssSpdAnalyzeSI(KmlScasolverTask **pHandle);

int KmlScadssSpdAnalyzeDI(KmlScasolverTask **pHandle);

int KmlScadssHpdAnalyzeCI(KmlScasolverTask **pHandle);

int KmlScadssHpdAnalyzeZI(KmlScasolverTask **pHandle);


#### 参数

| 参数名 | 类型 | 描述 | 输入/输出 |
| --- | --- | --- | --- |
| pHandle | KmlScasolverTask \*\* | 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 | pHandle为空。 |
| KMLSS\_BAD\_HANDLE | int | pHandle格式存在问题。 |


#### 依赖

#include "kml_scadss.h"


#### 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};
KmlScasolverTask* matrix_handle = NULL;
int ierr = KmlScadssSpdInitDI(&matrix_handle, n, a, ja, ia, MPI_COMM_WORLD);
ierr = KmlScadssSpdAnalyzeDI(&matrix_handle);
if (ierr != 0) {
printf("\nERROR in KmlScadssSpdAnalyzeDI: %d", ierr);
}
```
