说明：  给出正弦加噪函数，通过FFT,DTFT,做频谱变化，幅度谱和相位谱。(Sine plus noise function is given by FFT, DTFT, make changes in the spectrum, amplitude spectrum and phase spectrum.)

this document deescribed step by step approach to learn matlab programming easy and efficient way for beginners

系统分析课程设计。倒立摆的空间状态控制。自己设置参数，(Systems Analysis Course Design. Inverted pendulum control space state. Set up their own parameters,)

matlab code differential Algebraic Equation

说明：  根据TCH/FS信道的技术标准，用MATLAB语言编写程序模块，实现编译码模块功能，仿真TCH/FS信道各模块，检验与测试它们的性能，对TCH/FS信道的纠错性能进行仿真及分析。(under TCH/FS access to the technical standards, using MATLAB language program modules to achieve encryption module function, simulation TCH/FS Channel modules, test and test their performance, the TCH/FS channel error correction performance simulation and analysis.)

Arnold置乱变换的matlab代码，函数形式，做数字水印经常用到。(Arnold scrambling transform matlab code, functional form, so often used in digital watermarking.)

说明：  find all bases of digraph

使用matlab开发的短时傅立叶逆变换的例子，可以直接使用(Inverse short time fourier in matlab)

基于聚类的K中心点算法，附带说明文档，代码简单高效，很好的利用了矩阵的代数运算。数学思想较为高深，但通过仔细研读说明文档和动手操作，matlab数学分析能力可以得到有效的提高(K medoids clustering annotated document, the code is simple and efficient, good use of matrix algebra operations. Mathematical thinking is more profound, but by carefully studying the documentation and hands-on the Matlab mathematical analysis ability can be effective to improve)

此示意程序用DWT实现二维小波变换 1.调原始图像矩阵load wbarb 2.进行二维小波分解l=wfilters( db10 , l ) 3.分解结果显示figure(1) (This indicated procedures used to achieve two-dimensional wavelet transform DWT 1. Emphasized the original image matrix load wbarb 2. For two-dimensional wavelet decomposition l = wfilters (' db10' , ' l' ) 3. Decomposition results figure (1) )
