利用matlab模拟光纤中TE模的模式分布图。(Using matlab simulation model TE mode fiber distribution.)

Encryption algorithms are becoming more necessary to ensure data is securely transmitted over insecure communication channels. FOX is a recently developed algorithm and its structure is based on the already proven IDEA (International Data Encryption Algorithm) cipher. FOX is a symmetric (private key) block cipher. Its top-level structure uses the Lai-Massey scheme and the round functions used in the scheme are substitution permutation networks (SPN). Its flexibility lies in the fact that it can be efficiently implemented in hardware and software. We report some of the first results of implementing the cipher on an FPGA

《MATLAB7.0编程基础》书中图形的源代码，这是第2章的集合，比较全面，很有用，是很好的参考。(" Matlab7.0 programming foundation graphics source code in the book, which is a collection of Chapter 2, more comprehensive, useful, is a good reference.)

基于MATLAB的Walsh函数的产生.在MATLAB程序仿真部分，主要分为6大部分，分别为主函数，发送模块，接收模块，AWNG信道，Walsh函数和差错计数器。(Walsh functions generated based on MATLAB.MATLAB simulation program in part, is divided into six parts, the main functions are sending module, receiver module, AWNG channel, Walsh functions and error counters.)

可轻松实现短时傅里叶变换及对应逆变换，可更改程序内部窗函数，自行选择合适窗函数进行分析(Short-time Fourier transform and corresponding inverse transform can be easily realized. The internal window function of the program can be changed and the suitable window function can be selected by oneself for analysis.)

说明：  这个Matlab程序实现了MAP算法-最大后验概率算法，同时包括对算法有：卷积编码、卷积解码，BPSK，AWGN。同时绘制它的误码率和SNR(信噪比)。(The Matlab program achieved a MAP algorithm- maximum a posteriori probability algorithm, at the same time including the algorithm are: convolutional coding, convolution decoding, BPSK, AWGN. At the same time rendering its error rate and SNR (signal to noise ratio).)

说明：  输入圆的半径求周长和面积。程序由三个函数组成：主函数进行输入输出和函数调用，perimeter函数求周长，area函数求面积。(Enter the radius of the circle circumference and area requirements. Program consists of three functions: the main input and output functions and function calls, perimeter function evaluation perimeter, area function for the area.)

移动最小二乘MLS是无网格近似的基础,代码为ID,但适用于高维问题(mobile MLS is not the least square grid similar to the basis for the ID code, but applied to the high-dimensional problems)
