现代社会发展要求通信系统功能越来越强，性能越来越高，构成越来越复杂；另一方面，要求通信系统技术研究和产品开发缩短周期，降低成本，提高水平。这样尖锐对立的两个方面的要求，只有通过使用强大的计算机辅助分析设计技术和工具才能实现(Social development of modern communication systems require increasingly strong, the performance is getting higher and higher, which constitute more and more complex On the other hand, communications systems technology research and product development to shorten the cycle, reduce costs, improve the level. This in sharp opposition to the two requirements, only through the use of powerful computer-aided analysis and design techniques and tools can be achieved)

substitution cipher is the method of encoding in which unit of plain text are replaced by cipher text. Monoalphabetic cipher uses a fixed message over entire message.A monoalphabetic cipher uses fixed substitution over the entire message.The monoalphabetic substitution takes a letter of an alphabet and substitutes it with another letter, this way a ciphertext is generated. The way of converting is fixed. A character of the plaintext will be replaced by the same ciphertext character, during the entire ciphertext. There is no additional key. The only way of security is to keep the substitution-table secret. A popular example for the monoalphabetic substitution is the caesar cipher.

good demo of neural networks!

本程序通过调用matlab提供的信号分析函数对脑电信号进行分析变换，对信号处理工作具有很大帮助。(This procedure provided by calling matlab EEG signal analysis function analysis of transformations, the signal processing of great help.)

自己写的matlab版本的径向对称定位眼睛虹膜的程序 效果相当不错 吐血推荐给大家了 希望大家用的时候惦记着开发者的一番心血(Matlab write their own version of the radial symmetric positioning of the eye iris procedures recommended by the effect of good blood to all the hope that by the time the developers concerned about a blood)
