matlabr2008a的下载和安装详细过程，非常好用，比一般网上找的下载安装要好的多了(matlabr2008a the download and installation process in detail, very easy to use, than the general Internet is far better to download and install more)

AR模型,用经典法的自相关法求谱估计，简单实用(AR model, using the classic method of auto-correlation spectral estimation method, simple and practical)

梯度域实现色调映射 利用matlab函数实现fattal算法(Gradient Domain HDR Sourcecode)

Adobe Photoshop toolbox.Version 1.0 13-Dec-2006。photoshop中的matlab工具包，包括54个M文件，能够实现在matlab中调用photoshop的操作函数，并将处理结果传回matlab.也可以将matlab工作空间里的图像矩阵传送到photoshop中进行处理并动态返回结果. 该工具包从CS4中提取得到(其他版本没有测试过！)，安装时直接解压缩到photoshop文件夹下，按照压缩包中的pdf说明文档在matlab中添加路径后即能够使用，并能够在help中看到一个photoshop toolbox.(Adobe Photoshop toolbox.Version 1.0 13-Dec-2006. photoshop in matlab toolkit, including 54 M files, photoshop function call operation can be achieved in matlab, and the results returned matlab. too matlab workspace in the image matrix can be transferred to photoshop for processing and dynamic returns the result. toolkit extract obtained from CS4 (other versions not tested!), unzip the installation directly to photoshop folder, according to the compressed package in matlab pdf documentation can add the path after use, and can see in the help of a photoshop toolbox.)

对一段振动信号emd分解后，求每个分量的峭度值，选取峭度最大的分量，求其包络谱，能够明显看出特征频率。(After a period of vibration signal emd decomposition, seeking kurtosis value of each component, the largest component of kurtosis, seeking its envelope spectrum, can obviously see that the characteristic frequency.)

永磁同步电机的一个仿真模型，使用了电流和转速双闭环控制。(Permanent magnet synchronous motor, a simulation model, using the two-loop current and speed control.)

主程序为颗粒大小介质媒质有效传播常数的计算(Main program for the calculation of effective propagation constant under the quasicrystalline approximation with coherent potentail approximation (QCA-CP) for a medium with particle size distribution )
