绘制matlab图标，这个是演示程序，大家可以学习一下，多多交流，多多模仿(Draw the the matlab icon, this is the demonstration program, we can learn a lot of exchanges, a lot of imitation)

matlab对语音信号滤波，并比较滤波前后的音效。(matlab on the voice signal filtering, and compare the sound before and after filtering.)

求图像二维灰度直方图的matlab程序,讲述了如何用MATLAB去编写二维灰度直方图.(Seeking two-dimensional gray scale image histogram matlab program, describes how to use MATLAB to write two-dimensional histogram.)

说明：  matlab涉及到数据的导入的方法，用matlab做实验研究的同学可以下载看看！(the methods of adding datas into programms ,the dscription is very elebrate!!!)

协作通信仿真实例。通过三种不同协作方式，实现通信的仿真。效果很好！(matlab cooperation communications)

满足分数布朗运动的资产价格的走势的模拟程序。(Value s Simulation)

在本演示中，一个简单的图像检索方法，提出基于图像的颜色分布。用户只需提供一个“例子”的形象和搜索是基于这个例子（例如基于查询的图像）。包括图像和教学指令!!!(In this demo, a simple image retrieval method is presented, based on the color distribution of the images. The user simply provides an "example" image and the search is based upon that example (query by image example). Experiment image and instruction included!!!)

说明：  遗传算法matlab工具 1.工具箱文件拷贝至Matlab文件夹下，具体路径为：C:\program files\MATLAB\R2009a\toolbox。 2.工具箱路径加入Matlab文件路径之中。 流程为：File-->Set Path-->Add Folder。即，将C:\program files\MATLAB\R2009a\toolbox\文件夹加入该路径系统中。 3 重新启动Matlab，运行即可。 4 一般情况下，会出现如下情况。 安装遗传工具箱后出现问题：Warning: Name is nonexistent or not a directory: \afs\eos\info\ie\ie589k_info 解决方案： 将C:\program files\MATLAB\R2009a\toolbox\文件夹下的startup.m文件中的路径“\afs\eos\info\ie\ie589k_info\”改为goat当前所在的目录，“C:\program files\MATLAB\R2009a\toolbox\”即可。(Genetic algorithm matlab tool 1. Matlab toolbox files are copied to the folder, the specific path is: C: \ program files \ MATLAB \ R2009a \ toolbox. 2. Matlab toolbox add the file path into the path. Process is: File-&gt Set Path-&gt Add Folder. That is, the C: \ program files \ MATLAB \ R2009a \ toolbox \ folder by adding the path system. 3 Restart Matlab, can be run. 4 Under normal circumstances, there will be the following. Problems after installing genetic toolbox: Warning: Name is nonexistent or not a directory: \ afs \ eos \ info \ ie \ ie589k_info \ Solution: C: \ program files \ MATLAB \ R2009a \ toolbox \ startup folder under the . m file path &quot \ afs \ eos \ info \ ie \ ie589k_info \&quot to the current directory where the goat, &quot C: \ program files \ MATLAB \ R2009a \ toolbox \&quot can be.)

说明：  一些小波分析的有用程序 能帮助大家更好的理解一些小波变换和小波的主要功能(wavelet)

function named myresize and scale_image to resize and scale images in matlab
