digital signal prossing

演示AR序列的特征值、自协方差函数和谱密度。程序是开放的，可以修改参数(Eigenvalues ​ ​ demo AR sequence autocovariance function and spectral density. The program is open, you can modify the parameters)

有用的几个动力学物理量。包括自相关函数(acorr.m)，复杂度(complexity.m)，最近邻点(fnn.m)，局部非线性预测误差(nlpe.m，Shannon复杂度（Shannon.m）,嵌入窗估计(window.m)(Several dynamic invariants and measures that may be useful. Included are algorithms for autocorrelation (acorr.m), complexity (complexity.m), false nearest neighbours (fnn.m), local nonlinear prediction error (nlpe.m), Shannon complexity (shannon.m) and the embedding window estimator (window.m). )
