这是一些模糊控制的SIMULINK模块，希望对大家有用(These are related to fuzzy control module, want to be useful)

steepest descent method

The Vigenère cipher is a method of encrypting alphabetic text by using a series of different Caesar ciphers based on the letters of a keyword. It is a simple form of polyalphabetic substitution.Though the cipher is easy to understand and implement, for three centuries it resisted all attempts to break it this earned it the description le chiffre indéchiffrable (French for the indecipherable cipher ). Many people have tried to implement encryption schemes that are essentially Vigenère ciphers.[3] Friedrich Kasiski was the first to publish a general method of deciphering a Vigenère cipher.Unlike the monoalphabetic ciphers, polyalphabetic ciphers are not susceptible to frequency analysis, as more than one letter in the plaintext can be represented by a single letter in the encryption.

用matlab的GUI做的一个数字信号处理系统，选择输入信号波形及频率，进行滤波、频域分析等等。(Using matlab to do the GUI of a digital signal processing system, select the input signal waveform and frequency for filtering, frequency domain analysis and so on.)

说明：  这是一个能够实现卡尔曼滤波的完整OFDM系统。(THE OFDM system with kalman)

用matlab分析处理了一段语音信号，实现了语音合成(Using matlab speech signal analysis and processing for a while to achieve a speech synthesis)

这是一个关于基于互信息的图像配准程序，是以matlab编写(This is a mutual information based image registration procedures, the preparation is matlab)

相控阵系统学习，包含线阵和矩形面阵的仿真，非常有参考价值。(Simulation learning of Phased array system learning,includeing linear and rectangular array，which is very valuable.)

说明：  高等光学仿真（matlab版）-光波导、激光书中部分程序(Higher optical simulation (matlab)- waveguide, the laser part of the program in the book)
