Analysis beam propagration using Finite Difference Beam Propagation Method (Analysis beam propagration using Finite Difference Beam Propagation Method)

说明：  主要实现数表建立，查找功能，实现对数据的管理(Mainly the number of tables to achieve the establishment of search functions, to achieve the data management)

matlab在信号处理中傅里叶变换的应用，大家可以参考一下(matlab Fourier transform in signal processing applications, we can refer to)

数值分析国外教材源代码 Atkinson Matlab (Atkinson Matlab )

说明：  将GPS得到的经纬度，大地坐标，通过高斯投影正算，得到平面直角坐标 文件大小不够，再增加了高斯投影的pdf文档(The longitude, latitude and geodetic coordinates obtained by GPS are corrected by Gauss projection, and the plane rectangular coordinates are obtained.)

Generatind dabechies wavelet using brute force algorithm

说明：  matlab写的运动检测 自动实现 十分有用的代码 值得学习！(Motion detection matlab automatically write the code should be very useful to learn!)

空间飞行器三轴稳定姿态动力学仿真，三轴稳定姿态动力学仿真(Stable attitude dynamics simulation of the space vehicle three weeks)

这个程序是MIMO通信系统的信道仿真，完成了MIMO系统中各种信道的仿真(This program is a MIMO communication system channel simulation, the completion of the MIMO system, the simulation of various channel)

ES is a symmetric block cipher. The same key is used to encrypt and decrypt the message. The plain text and the cipher text are the same size. The Aes algorithm works as follows: Convert to state array: This step consists of conversion on the matrix onto a state array operating with the sbox. Transformations (and their inverses) AddRoundKey: Computing the round key for each round. SubBytes: Substituting by bytes from Sbox. ShiftRows: Shifting of rows. MixColumns: Exor operation on columns. Key Expansion: Expanding the key to be used on next round.
