java中是否有一个函数可以获得移动平均值 [英] Is there a function in java to get moving average

问题描述

我遇到需要每0.5秒从设备处理5000个样本的情况。

I have a situation where I need to process 5000 samples from a device in every 0.5 sec.

假设窗口大小为100，那么移动平均线将产生50个点。我正在尝试使用传统方法，即使用循环。但这是一种非常低效的方法。有什么建议吗？

Lets say the window size is 100, then there would be 50 points resulting from the moving average. I am trying with conventional method, i.e. with loops. But this is a very inefficient way to do it. Any suggestions ?
