MIMO

a source code for application of genetic algorithm in MWTMP problems.

matlab从入门到精通全书源代码，希望对大家有用(matlab book from entry to the master source code, useful for all of us hope)

The function to obtain indexes of inner of window points in the windoving procedure for each point in 2D surface. It allows to avoid cyclic operation which too slowly.

image segmentation with GMM

说明：  it is to rotat the imag n reg it

一个实例搞定MATLAB界面编程,极易上手(An instance to get the the MATLAB programming interface, easy to use)

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.

基于蒙特卡罗方法的试卷难度分布研究,Monte Carlo method based on the difficulty of distribution of papers(Monte Carlo method based on the difficulty of distribution of papers)

说明：  对埃克曼风海流进行数值模拟，观察不同风速下风海流的结构差异以及风海流结构随时间的差异。(The numerical simulation of Ekman wind current is carried out to observe the structure difference of wind current under different wind speed and the difference of wind current structure with time.)

多带KALMAN滤波，是不错的程序，有兴趣的可以下了(Multi-band Kalman filtering, is a good procedure, interested parties can have a)
