| --- | --- | --- |
| NO\_ERROR | int | 正常执行。 |
| KML\_SOLVER\_INVALID\_ARGUMENT | int | 无效的参数。 |


#### 依赖

#include "kml_iss.h"


#### 示例

C Interface：

```
KmlSolverTask *handle
int n = 8;
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 };
int ja[17] = { 0,3,4,1,2,3,5,2,7,3,6,4,5,5,7,6,7 };
int ia[9] = {0, 3, 7, 9, 11, 13, 15, 16, 17};
int ierr;
ierr = KmlIssCgInitDI(&handle, n, a, ja, ia);
ierr = KmlIssCgAnalyzeDI(&handle);
ierr = KmlIssCgFactorizeDI(&handle);
