This matlab code about how to design antenna in MIMO

matlab的物理应用，对做物理实验的数据处理很有帮助(matlab physical application to do physics experiments data processing helpful)

数据矩阵运用非负矩阵分解算法，分解得到两个低维矩阵，并用于信号分离。(The data matrix is decomposed into two low-dimensional matrices by non-negative matrix decomposition algorithm and used for signal separation.)

greypred.rar用于GDP预测，较为精准，误差小，程序简单，容易操作，实用。是很好的预测程序。(liner fit)

说明：  用MATLAB编程实现半导体光放大器（SOA）的ASE噪声特性分析，可以计算半导体光放大器的载流子密度，ASE增益，噪声指数，主要用的是半波逼近法来实现数值算法。(Programming with MATLAB semiconductor optical amplifier (SOA) of the ASE noise characteristics analysis, semiconductor optical amplifiers can calculate the carrier density, ASE gain, noise figure, the main use is half-wave approximation method to achieve the numerical algorithm.)

这个程序是用格雷码的基带仿真，在加高斯白噪声的情况下仿真ber和ser曲线(the purpose of this m-file is to show a baseband simulated version of QPSK with Gray coding( Rayleigh multipath and AWGN added) which may give valid results)

通过一系列教学实例，帮助学生很好的理解matlab中的符号运算实现微分、积分（定积分与不定积分）、极限、级数、绘图等常用功能，几乎可以推导高数中的绝大部分公式，也可用于理论公式推导。(Through a series of teaching examples to help students a good understanding of symbolic computation matlab achieve differentiation, integration (with the definite integral indefinite integral), ultimate, series, graphics and other commonly used functions can be derived almost most of the high number of formulas can also be used to derive theoretical formulas.)

一系列关于信道仿真的基于Matlab的代码，相关的链路级仿真，十分详细(Series of channel simulation based on Matlab code, the associated link level simulation, very detailed)

说明：  利用Matlab做面板数据分析（平行数据分析）的一个实例(Use Matlab to do analysis of panel data (parallel data analysis) is an example of)
