重要的格林函数程序，好不容易找到的，希望对大家有用(the matlab code of Green function)

说明：  灰度门限化许多情况，图象是由具有不同灰度级的两类区域组成。如文字与纸张、地物与云层（航空照片）。其特点:直方图具有两个峰，分别与两个灰度级范围相对应 。故可选择一个门限，将两个峰分开。(Gray threshold of many cases, the image is gray level of two different regional groupings. If words and paper, surface features and cloud cover (aerial photograph). Its features: histogram has two peak, respectively, with the two gray-scale range corresponding to. So choose a threshold, separating the two peaks.)

多径衰落信道matlab仿真程序，有说明(multi-path flat fading)

加权平均法是DEM移动内插法的特例，是一种简化的逐点内插法。它是先以内插点为中心，确定一个取样窗口，然后计算落在窗口内的采样点的特征值的平均值，作为内插点的特征值的估值，(The weighted average method is a special case of the DEM mobile interpolation, a simplified point-by-point interpolation. It is the first interpolation point as the center, to determine a sample window, and then calculate the average of the characteristic values ​ ​ of the sample points falls within the window, the valuation of the points of the feature value as the interpolation,)

matlab判别分析，基本思想是将高维的模式样本投影到最佳鉴别矢量空间，以达到抽取分类信息和压缩特征空间维数的效果，投影后保证模式样本在新的子空间有最大的类间距离和最小的类内距离，即模式在该空间中有最佳的可分离性。(matlab discriminant analysis, the basic idea is to sample the high-dimensional pattern projected onto the optimal discriminant vector space, in order to achieve the classification of information extraction and compression feature space dimension effect, the projected sample assurance model in the new subspace has the largest class room the intra-class distance and the minimum distance, i.e., have the best separability pattern in the space.)

盲均衡算法实现的有噪声信道下的4QAM调制解调，并画出算法的收敛图(Blind equalization algorithm of noisy channel under the 4QAM modulation and demodulation, and draw the convergence map)

使用matlab仿真一个ofdm真实环境的步骤介绍，英文介绍很详细(Matlab simulation ofdm using a step in the real environment, the English introduced in detail)

计算机控制系统程序，包括计算机系统的模拟化设计方法，离散化设计方法，对嵌入式系统的认识。(Computer control system program includes the continuous design method ,the discrete design method of computer system,and the understanding of embedded systems. )

VB调用Matlab制作的COM组件实现二者混合编程，本文章主要介绍在MATLAB中编写com组件，为了检验结果的正确性，在工程地质中要用到这项技能。（郑重声明：本资料是借用张赛民老师的成果，张赛民老师为第一作者，未经允许，不得用于商业用途）(VB COM component calls made to achieve both Matlab programming mix, this article focuses on com components written in MATLAB, in order to verify the correctness of the results, in engineering geology to use this skill.
