matlab代码，用于三维显示的，我在外国ftp下的(matlab code for three-dimensional display)

Markov chain, 4 states, calculate antocorrelation

说明：  matlab下看地震切片的程序，配合seislab使用(matlab seismic sections look at the procedure, coupled with the use of seislab)

说明：  这是matlab中进行矩阵LU分解的代码。是一个包，集合了模拟LU分解所需的函数文件。(A function for matrix LU factorization.This is the first function.There are another three function named "bslashtx","forward","backsubs".)

LDPC码既低密度奇偶校验码（Low Density Parity Check Code，LDPC），它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低, 结构灵活，是近年信道编码领域的研究热点，目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G) (LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.)

multiple antanna signal generation program

阵列信号处理中的其中一个传统子空间方法仿真程序，二维music算法。(One of the traditional subspace method simulation program in array signal processing, the two-dimensional music algorithm.)

通过史密斯圆图进行相关计算 求得输入阻抗( Correlation calculation determined by the input impedance Smith chart)

学习MATLAB的书籍，包括官方学习手册，MATLAB编程风格指南，编程实例，基础教材等！(Learning MATLAB books, including official study manual, MATLAB programming style guide, programming examples, basic teaching materials, etc.!)

说明：  主要用于基于TDOA测距定位的卡尔曼滤波，(TDOA ranging mainly used for location-based Kalman filter,)
