Matlab M-Files:There are four ways of doing code in Matlab. One can directly enter code in a terminal window. This amounts to using Matlabas a kind of calculator, and it is good for simple, low-level work. The second method is to create a script M-fi le. Here, one makes a fi le with the same code one would enter in a terminal window. When the fi le is “run”, the script is carried out. The third method is the function M-fi le. This method actually creates a function, with inputs and outputs. The fourth method will not be discussed here. It is a way to incorporate C code or FORTRAN code into Matlab this method uses .mex fi les. We will not disucss it here.

实现边界正择性测量，可在MATLAB环境下运行(the border is optional measurement, in the MATLAB environment running)

说明：  利用matlab强大的数据处理功能和图形化功能来对信号进行处理，这是吴镇扬的数字信号处理第五次实验的全部代码，可用来参考(Using matlab powerful data processing and graphical capabilities of signal processing, which is the fifth digital signal processing Zhen-Yang Wu experiment all of the code can be used to refer to)

简单的if else，和switch分支的小程序，希望大家谅解(Simple if else, and switch branches applet, I hope you understand)

这个是matlab里基于维纳滤波算法对模拟运动模糊并加入高斯噪声的图像进行复原的程序 (This is where Wiener filtering algorithm matlab simulation of motion blur and add Gaussian noise image recovery program based on conduct)

说明：  这是一个基于瑞利衰落信道的LS算法的Matlab程序，希望对大家有用。(This is based on a Rayleigh fading channels LS algorithm Matlab procedures in the hope that useful for all.)

Neural Predictive Control using Quasi Newton Optimization

A polyalphabetic cipher is any cipher based on substitution, using multiple substitution alphabets. The Vigenère cipher is probably the best-known example of a polyalphabetic cipher, though it is a simplified special case.Polyalphabetic substitution ciphers are useful because the are less easily broken by frequency analysis, however if an attacker knows for instance that the message has a period n, then he simply can individually frequency analyze each cipher alphabet. The number of letters encrypted before a polyalphabetic substitution cipher returns to its first cipher alphabet is called its period. The larger the period, the stronger the cipher. Of course, this method of encryption is certainly not secure by any definition and should not be applied to any real-life scenarios.
