svpwm,实例，三电平正常运行，simulink仿真(SVPWM instance simulation, three level, normal operation)

对电磁波三维传播的仿真，包括在自由空间的传播和FDTD算法的有界空间传播(Three-dimensional simulation of electromagnetic wave propagation, including propagation in free space bounded space propagation and FDTD algorithm)

调整pdf的边缘及其行间距大小。首先把pdf保存为图片，然后用此程序调整边缘或行间距大小，把修改后的图片重新整合成pdf。此软件的目的是为了kindle用户编写。因为kindle的屏幕有限，除去多余的边缘和行间距，可以使kindle读书效率更高，减少过多翻页操作。(Adjust the line spacing pdf and the size of the edge. First, save the pdf as a picture, and then use this procedure to adjust the size of the edge or line spacing, the re-integration of the modified images into pdf. The purpose of this software is to kindle the user to write. Because of the limited screen kindle, to remove the extra edge and line spacing can make reading more efficient kindle, to reduce excessive flip operation.)

This is a simple script two illustrate the concepts of Probability density function(pdf) cumulative density function (cdf). Two help pdfs are also included to understand the pdf and cdf concepts.

自己编写的基于多特征目标跟踪的算法，能实现实时跟踪(I have written based on multi-feature target tracking algorithm, to achieve real-time tracking)

13位巴克码和线性调频的联合调制码元的频谱程序，可以自由设定起始频率和更变码元(this matlab code is suitable of 13barker code and LPM,you could give start frequency and end frequency)

对读入的图片做霍夫变换，识别出图片中的直线并输出。(Do the Hough Transform to the input image, that is to detect lines in the input image, and output those lines.)

bulit base on ISCAS paper example to reference to paper, we can use the tool to repeat the action of the author(it s an assistance toolbox of the paper to understand what the author say)
