说明：  matlab环境下图象图形处理的基本函数的介绍以及简单示例(matlab environment images deal with the basic function of graphical presentation, as well as simple examples)

先进 PID 控制及其 MATLAB 仿真 （程序）教材及书中的matlab程序(Advanced PID Control and MATLAB Simulation (program) matlab program materials and books)

Our project is to describe the Brownian Motion and Geometric Brownian Motion. This project is to simulate the price shock. Then we use Geometric Brownian motion to describe the movement of shocks’ price. The program is produced by Matlab.(Application of Ito’s Lemma to a Stock Price Process)

需将图形文件复制到D盘根目录，或修改程序中的相关文件的路径。 计算机运行可能会出现这样的警告：Warning: Function call WAVEDEC2 invokes inexact match F:Matlab oolboxwaveletwaveletwavedec2.m. > In Wnn0802 at 18 无妨，没关系的，不影响运算结果。(Need to copy files to the D graphics root directory, or modify the program in the path of the relevant documents. Computer running such a warning might appear: Warning: Function call WAVEDEC2 invokes inexact match F: Matlab toolbox wavelet wavelet wavedec2.m> In Wnn0802 at 18 anyway, it does not matter, does not affect the result of the operation.)

通过matlab彩色图像转换成灰度图像，再图像旋转，然后画布扩大，最后均值插值(Matlab color images through the gray image into another image rotation, and then expand the canvas, and finally the mean interpolation)

用matlab对wav文件采用不同的方式读取（wavread和fopen），并对其进行低通滤波处理。滤波用的fir直接型低通滤波器(to read the wav file in different ways with Matlab (wavread, and fopen), and then low-pass filtering. the low-pass filter is direct_type FIR filter )

将Excel里面的大量数据导入MATLAB软件里面进行画图(A large amount of data in Excel is imported into MATLAB software for drawing)

一本关于复杂网络的文献，对从事这方面研究的人员是特别有帮助的。(About a complex network of literature in this field of research staff are particularly helpful.)
