用斜率的方法来求时间序列的lyapunov exponent,在非线性动力学和时间序列处理中经常用到。很实用的小程序。(slope of the methods used to the time series for the lyapunov exponent. Nonlinear Dynamics and the time sequence processing frequently used. Very small practical procedures.)

This function computes the RMS feature of the signals in x,which are stored in columns. The signals in x are divided into multiple windows of size winsize and the windows are space wininc apart. Inputs x: columns of signals winsize: window size (length of x) wininc: spacing of the windows (winsize) datawin: window for data (e.g. Hamming, default rectangular) must have dimensions of (winsize,1) dispstatus:zero for no waitbar (default) Outputs feat: RMS value in a 2 dimensional matrix dim1 window dim2 feature (col i is the features for the signal in column i of x)
