kml_?_spline_min_size

返回插值对象spline所需要的最小的点的数量。例如，三次插值最小需要3个点。

接口定义

unsigned int kml_float_spline_min_size(const kml_float_spline *spline)

unsigned int kml_double_spline_min_size(const kml_double_spline *spline);

参数

参数名	类型	描述	输入/输出
spline	kml_float_spline, kml_double_spline	插值对象指针。	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));
float x = 1;
float y = 0;
kml_float_spline *spline = kml_float_spline_alloc(kml_float_interp_cspline, xSize);
size_t min_size = kml_float_spline_min_size(spline);
