说明：  最大李雅普诺夫指数的计算 该函数用来计算时间序列的最大Lyapunov 指数--Wolf 方法 ％ m: 嵌入维数 ％ tau:时间延迟 ％ data:时间序列 ％ N:时间序列长度 ％ P:时间序列的平均周期,选择演化相点距当前点的位置差，即若当前相点为I，则演化相点只能在|I－J|>P的相点中搜寻
(The largest Lyapunov exponent calculation of the function used to calculate the time series of the largest Lyapunov index Wolf method m: embedding dimension tau: time delay data: time series N: time-series length P: Time-series average cycle , select evolution with distance of the location of the current point difference, that is, if the current points for the I, the evolution of phase points can only be | I-J |)
