| spline | kml\_float\_spline2d\*, kml\_double\_spline2d\* | 插值对象指针。 | 输入 |


#### 依赖

#include "kipl.h"


#### 示例

```
const size_t xSize = 4;
const size_t ySize = 4;
float xArr[4] = {1,1.33,1.67,2};
float yArr[4] = {1,1.33,1.67,2};
float* zArr = (float*)malloc(xSize * ySize * sizeof(float));
kml_float_spline2d *spline = kml_float_spline2d_alloc(kml_float_interp2d_bicubic, xSize, ySize);
kml_float_spline2d_init(spline, xArr, yArr, zArr, xSize, ySize);
kml_float_spline2d_free(spline);
```
