说明：  这个事matlab作图的一个ppt演示范本，希望对大家有用(The matter of a ppt presentation matlab mapping model, we want to be useful)

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. The  energy as a normal distribution (15,3).  1 energy losses in the substrate surface to walk.  point particles that 3 energy loss in the encounter with the other particles.  by the lower diffusion tops every diffusion layer, a loss of 4 energy diffusion from high to low, the energy loss of 3.  When the energy of the particles is less than or equal to 0:00 stay down, add 1 to the number of particles that point.  critical nucleus size of 10 particles.  these points, depending on the number of particles of each point is displayed in a different shade. Point, the brighter, the thicker the point of the fi)

使用matlab写的6个多用户检测程序，非常有价值(Using matlab written more than 6-user detection procedures, very valuable)

一些简单最优化方法的matlab实现，及一些方法(Some simple optimization method matlab implementation)

4 program for adaptive filters (LMS & SER algorithm with 2 example)

本程序是采用正交匹配算法实现图像LENA的压缩传感,而且该程序没有经过任何优化处理。(This program is the use of orthogonal matching algorithm for image compression LENA sensing, and the program has not been any optimization.)

关于PID控制的一些例程，与薛定宇老师的反馈控制配套，与大家一起分享(PID control on a number of routines, and Xue Dingyu teacher feedback control facilities, and shared with)

产生16路信号，画出16路原始信号的频谱叠加图以及滤波器响应，并画出结果信号的时域和频域波形(Generate 16-channel signal, draw 16 original signal spectrum overlay and a filter response, and draw result signals in time domain and frequency domain waveforms)
