单极性PWM控制方式Simulink仿真，很简单，便于电力电子初学者学习，里面还加了一个模拟滤波器，也很简单，但想法非常重要(Unipolar PWM control Simulink simulation, very simple, easy for beginners to learn power electronics, which also added a simulated filter, is also very simple, but very important idea)

丹麦技术大学的J爀最攀渀 Arendt Jensen教授开发的医学超声成像Field Ⅱ仿真安装程序(The Technical University of Denmark, developed by Prof. Jrgen Arendt Jensen Field Ⅱ medical ultrasound imaging simulation setup)

基于双边滤波的高动态图像显示，把10位的图像显示在8位的显示器上( High dynamic image display based on bilateral filtering)

画出地球，模拟不同时刻卫星位置，模拟用户位置，与可见卫星(Draw the earth, the simulation satellite location, different time simulated user s location, with the visible satellites)

说明：  Basic on transfrom an image

Time_FFT_PeakPlot.zip It is a function code.

用于大气辐射传输模型modtran5的matlab程序，可读取编辑tape5文件，运行modtran以及读取运行结果。(It provides a set of functions (called “methods” in object-oriented programming terminology) that ease the handling of MODTRAN cases. These include methods to read the tape5 file format into a Mod5 class “instance” or “object”, alter the case instance described in the file, write the tape5 format back to a file, run MODTRAN on the case and read various results from MODTRAN output files back into Matlab.)

为使随机序列具有相关性，这里是相关高斯序列生成的一种方法(co rrelated Gaussian sequences)
