中文说明：计算李雅普诺夫指数的MATLAB文件，李雅普诺夫指数表示相空间相邻轨迹的平均指数发散率的数值特征。又称李雅普诺夫特征指数，是用于识别混沌运动若干数值的特征之一。
English Description：
By calculating the Lee Yap Andrianof exponent of the MATLAB document, the Lee Yap Andrianof exponent represents the numerical characteristic of the mean exponential divergence rate of the adjacent trajectories in the phase space. Also known as Lee Yap Andrianof feature index, is used to identify the chaotic motion of a number of numerical characteristics.
