假设我有一个双精度数组,那么用什么样的算法对这个系列进行采样呢?
Akima interpolation
?我太笨了,不能把数学描述翻译成代码。
// values is an array of doubles
// idx is the index of the left-hand value for the current interpolation
// t is the normalized parameter between values[idx] and values[idx+1]
// Don't worry about array bounds, I'll handle that separately.
public double InterpolateAkima(double[] values, int idx, double t)
{
...?
}
