A310飞机的数学模型!能够完整的表现该飞机的气动模型！！！！！！！！(The math model of A310 aircraft!)

Example of using Matlab to determine text entropy.

计算分数阶傅里叶变换，为一维的。是Pei/Yeh/Tseng的源码。(Compute discrete fractional Fourier transform of order a of vector f according to Pei/Yeh/Tseng)

被控对象为G(S)=400/（s*s+500s）,首先运行模糊控制器程序chap4_2.m,并将模糊推理系统保存在a2中，然后运行模糊控制SIMULIK程序。位置指令为0.5sin（10t）,simulink见chap4_3(Controlled object is G (S) = 400/(s* s+500s), first run the fuzzy controller program chap4_2.m, and stored in a2 fuzzy inference system, and then run the fuzzy control SIMULIK program. Position command is 0.5sin (10t), simulink see chap4_3)

说明：  很好用的NB分类器，有助于理解和掌握NB网络，欢迎大家下载(Very good NB classifier, help to understand and master the NB networks, welcome everyone to download )

说明：  Binary Genetic Algorithm

本程序为利用给定节点，求未知节点插值法，包括拉格朗日插值法和牛顿向前插值法(This procedure for the use of a given node, seeking the unknown node interpolation method, including the Lagrange interpolation method and Newton' s forward interpolation)

matlab, this is Ljapunov (variant2) function for linear unstable system

这是一个C均值算法的Matlab程序,已测试可用，希望对大家有帮助！(This is a C means algorithm Matlab program has been tested is available, we want to help!)

Data Encryption by Matrix Multiplication We will only use numbers 0 to 26 for the encryptive mathematics operation. Numbers from 1 to 26 are for letters from A to Z and 0 is for all non-letter characters. To minimize usage of numbers, all letters are converted to upper case. The original message is converted to number array according to the ASCII table and minus 64. We partition whole array into blocks of 8 numbers. The last block may be added several zeros. Then multiply each block by the an 8x8 matrix A which is invertible in Z27 to get cipher data. The decryption is the same process except to use its inverse matrix B. For good visual reading, we convert all non-letter characters to under score for the decryption.
