这里是一段使用C语言实现某种缓和曲线拟合算法的代码:
```
#include <stdio.h>
#include <math.h>
#define MAX_POINTS 100
struct Point {
double x;
double y;
};
int n;
Point points[MAX_POINTS];
double easing(double t) {
return t * t * (3 - 2 * t);
}
double interpolate(double t) {
int index = (int)(t * (n - 1));
double fraction = t * (n - 1) - index;
return points[index].y * (1 - easing(fraction)) + points[index + 1].y * easing(fraction);
}
int main() {
// Read points from input
scanf("%d", &n);
for (int i = 0; i < n; i++) {
scanf("%lf%lf", &points[i].x, &points[i].y);
}
// Evaluate and output curve at several points
for (double t = 0; t <= 1.0; t += 0.1) {
printf("%.2lf, %.2lf\n", t, interpolate(t));
}
return 0;
}
```
其中,函数 `easing` 实现了缓和曲线算法,函数 `interpolate` 则是利用该算法实现拟合曲线的过程。
