说明：  ARMA模型时间序列分析法简称为时序分析法，是一种利用参数模型对有序随机振动响应数据进行处理，从而进行模态参数识别的方法。参数模型包括AR自回归模型、MA滑动平均模型和ARMA自回归滑动平均模型。这里给出了一个求出ARMA模型参数的MATLAB程序。
(ARMA model time series analysis method, referred to as time series analysis method, is a method of using parameter model to process the random vibration response data, so as to identify the modal parameters. The parametric models include ar autoregressive model, Ma moving average model and ARMA autoregressive moving average model. This paper presents a matlab program to calculate the parameters of ARMA model.)
