void kml_double_interp_free(kml_double_interp *interp);


#### 参数

| 参数名 | 类型 | 描述 | 输入/输出 |
| --- | --- | --- | --- |
| interp | kml\_float\_interp\* / kml\_double\_interp\* | 指向插值对象的指针。 | 输入 |


#### 依赖

#include "kipl.h"


#### 示例

```
const size_t xSize = 4;
float xArr[4] = {1,1.33,1.67,2};
float* yArr = (float*)malloc(xSize * sizeof(float));
kml_float_interp *interp = kml_float_interp_alloc(kml_float_interp_cspline, xSize);
kml_float_interp_init(interp, xSize, xArr, yArr);
kml_float_interp_free(interp);
```
