# kml_?_spline_free

释放插值对象spline。

#### 接口定义

void kml_float_spline_free(kml_float_spline *spline)

void kml_double_spline_free(kml_double_spline *spline);


#### 参数

| 参数名 | 类型 | 描述 | 输入/输出 |
| --- | --- | --- | --- |
| spline | kml\_float\_spline\* / kml\_double\_spline\* | 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_spline *spline = kml_float_spline_alloc(kml_float_interp_cspline, xSize);
kml_float_spline_init(spline, xSize, xArr, yArr);
kml_float_spline_free(spline);
```
