说明：  毕业用的时间序列混沌分析，里面吧包含相空间重构，李雅普诺夫指数求取，小波去噪等等(Graduated with a chaotic time series analysis, which it contains the phase space reconstruction, Lyapunov exponent for wavelet denoising, etc.)

说明：  凸优化程序包，包含各种凸优化算法,可供方便调用.(Convex optimization package, contains a variety of convex optimization algorithm, for convenience call.)

2阶Runge_kutta解微分方程 调用格式同ode45， f为微分方程函数，a b为积分区间，x0初值 h为步长，默认为0.001(Differential Equation of Order 2 Runge_kutta call format with ode45, f for the differential function, ab for the integration interval, x0 h for the initial step, the default is 0.001)

分类算法，参数分别为G（相似度矩阵），r（邻居门限），lambda（类门限），返回值A，一个cell数组，每个元素是一个向量，包含了一个类的所有元素。(Classification algorithm parameters are G (similarity matrix), r (neighbor threshold), lambda (class threshold), the return value A, a cell array, each element is a vector containing all the elements of a class.)
