find_peak
从曲线中检测到其峰值:先利用二次求导得到所有凸点,设置门限,去除过低的凸点,然后利用滑动窗的方法,在凸点中求得满足峰值要求的点(Detected from the curve to its peak: the first use of the second derivative method to get all the bumps, set the threshold too low to remove the bumps, and then use a sliding window, obtained in a bump to meet peak requirements of point)

arma_analysis
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 for time series analysis method referred to as time series analysis is a parametric model for the orderly use of random vibration data in response to treatment, thereby to carry out modal parameter identification method. Parameter model including the autoregressive AR model, MA model and ARMA moving average Autoregressive Moving Average Model. Here gives an ARMA model parameters are obtained MATLAB procedures.)
