这是一本经典的MatlAB书的习题代码，非常丰富，非常实用(This is a classic book of exercises code MatlAB, very rich, very practical)

用MATLAB实现动态系统的求导与积分函数(MATLAB diff and int)

说明：  关于非线性时间序列中同时计算关联维和Kolmogorov熵的程序,(on nonlinear time series simultaneously calculate the correlation dimension and Kolmogorov entropy procedures,)

说明：  主元分析方法（PCA）是一种基于多元统计分析的数据降维方法, 它利用过程变量间的相关关系, 建立正常工况下的主元模型, 通过检验新的数据样本相对于主元模型的背离程度, 从而发现异常和故障。 (Principal Component Analysis (PCA) is based on multivariate statistical analysis of the data reduction method, which uses the correlation between process variables and establish the normal condition of the main element model, by testing samples of the new data relative to the principal component model departure from, and thus abnormal and failure.)

S变换是一种时频分析方法，用于分析非平稳信号。(use S transform to process signal)

逆短时傅立叶变换源代码.适合于非稳态的时频联合分析,可直接用于MATLAB编程,无解压密码.(inverse Fourier transform source code. Suited to the non-steady-state joint time-frequency analysis can be used directly in MATLAB programming, without extracting passwords.)

对于N=11的标准线阵，分别采用如下波束形成器进行最优波束形成，要求含有干扰信号和噪声。 1、最小方差无失真响应（MVDR）波束形成器； 2、最小功率无失真响应（MPDR）波束形成器。(Minimum variance distortionless response (MVDR) beamformer Minimum power distortionless response (the MPDR) beamformer.)
