C#实现算术平均 滤波算法 输入List<double>返回List<double>

以下是 C# 实现算术平均滤波算法的代码，输入 List<double>，返回 List<double>：

public static List<double> ArithmeticMeanFilter(List<double> inputList, int windowSize)
{
    List<double> outputList = new List<double>();
    for (int i = 0; i < inputList.Count; i++)
    {
        if (i < windowSize - 1)
        {
            outputList.Add(inputList[i]);
        }
        else
        {
            double sum = 0;
            for (int j = i - windowSize + 1; j <= i; j++)
            {
                sum += inputList[j];
            }
            double mean = sum / windowSize;
            outputList.Add(mean);
        }
    }
    return outputList;
}
