QAM MIMO simulation using MATLAB

这个有中文注释，看得明白，在matlab环境中自动识别连通区域的大小,相控阵天线的方向图（切比雪夫加权）。( The Chinese have a comment, understand it, Automatic identification in the matlab environment the size of the connected area, Phased array antenna pattern (Chebyshev weights).)

全国研究生数学建模大赛2012年优秀参赛论文集D题1解法与程序(National Graduate Mathematical Modeling Contest 2012 entry Engineering D problem an excellent solution and Procedures)

本程序特别适合于弹道计算等方面使用。比ODE45函数的速度加快了很多，且程序充分展示了Matlab向量运算的强大功能，以及编程的简单快捷。(The program is especially suitable for ballistic calculation such as the use of. Than the ODE45 function more quickly, and it shows the powerful function of Matlab vector operations, and programming is simple and quick.)

This code detects object in a Video and indicates its position in each time frame and keeps track of it. The code is written in *.m format which is executable in MATLAB(This code detects object in a Video and indicates its position in each time frame and keeps track of it.

根据对真空蒸发镀膜的分析，在40×40的范围内分别蒸 发：1000、5000、10000、20000、30000个粒子。  利用2维数组记录每个点的粒子数。  初始粒的横纵坐标为0～40的均匀分布。  能量为（15，3）的正态分布。  在基体表面自由行走时损失1的能量。  若该点有粒子，即与其他粒子相遇时损失3的能量。  由低处向高处扩散，每扩散一层，损失4的能量，由高处 向低处扩散，损失3的能量。  当粒子的能量小于等于0时停留下来，该点的粒子数加1。  临界核的尺寸为10个粒子。  根据每个点粒子个数的不同，以不同的灰度显示这些点。 点越亮，则表示该点的膜越厚。  以图形方式显示粒子初始能量的正态分布情况(Based on the analysis of the vacuum evaporation coating, respectively, in the range of from 4040 evaporated: 1000,5000,10000,20000,30000 particles.  each point using 2-dimensional array to record the number of particles. The  initial grains transverse and longitudinal coordinates of a uniform distribution of 0 to 40.
