对灰度图像采用Arnold混沌加密，实现图像置乱加密(By Arnold on the gray image encryption, encryption of image scrambling)

说明：  用MUSIC方法实现谱估计的程序，可以用于频谱分析，(Spectrum estimation using MUSIC method implementation procedures can be used for spectrum analysis,)

说明：  最优化方法（防止限于局部最优等情况时）验证函数，以确定方法的有效性(Test functions)

雷达来波方向的DOA估计，本程序是利用matlab进行一维DOA谱峰搜索(Radar DOA DOA estimation, the procedure is carried out using matlab DOA one-dimensional spectral peak search)

实战matlab 并行程序设计 适合入门并行(Actual matlab parallel programming, suitable for entry parallel)

Source code in matlab of neural network.

图像的压缩编码（JPEG），可以下载看看(Image compression (JPEG), you can download to have a try)

简化的频域反馈判决反馈均衡器，系数不需要每次都更新。(simplified frequency decision feedback filter ，do not need to update factor everytime)

包含飞行器飞行中的姿态控制，如侧滑角，倾斜角，滚转角，俯仰角，这是第二能量熵的matlab代码，数据模型归一化，模态振动。( It comprises aircraft flight attitude control, such as slip angle, tilt angle, roll angle, pitch angle, This is the second energy entropy matlab code, Normalized data model, modal vibration.)

说明：  多尺度样本熵程序，实例中用于一段轴承故障数据，简单易懂。MultiscalePermutationEntropy函数中的PermutationEntropy也可以单独拎出来计算单个样本熵。(The multi-scale sample entropy program, which is used for a section of bearing fault data in an example, is simple and easy to understand. The permutationentropy in the multiscale permutationentropy function can also be carried out separately to calculate the entropy of a single sample.)
