建立自回归滑动平均时间序列模型ARIMA,用来预测未来数据值(time series model-ARIMA to predict the future value )

基本原理就是首先求解出连续系统微分方程的近似解，然后对系统的Jacobian矩阵进行QR分解，计算Jacobian矩阵特征值的乘积，最后计算出LE和分数维(The basic principle is to first find the approximate solution of differential equations continuous system, then the system will be on the Jacobian matrix QR decomposition product Jacobian matrix computing eigenvalues, and finally calculate the fractal dimension LE)

正确率可以达到98％，利用matlab写成的窄带噪声发生，使用高阶累积量对MPSK信号进行调制识别。( Accuracy can reach 98 , Using matlab written narrowband noise occurs, Using high-order cumulants of MPSK signal modulation recognition.)

说明：  优化算法，寻找全局最优解，放入matlab预设目录直接可以使用(optimization algorithm)
