三维Lee滤波，对三维SAR图像和超声波图像的相干斑进行抑制(3D Lee filter, three-dimensional SAR images and ultrasound images to suppress the speckle)

闭环充电机仿真图，看了这图你就会做充电机了。(Closed-loop simulation charts charger, read this plan you will do a charger.)

This is a matlab program. It will implement the estimation and testing procedures for a Markov switching parameter model as presented in B. Hansen "The likelihood ratio test under non-standard conditions: Testing the Markov trend model of GNP."

matlab gui, 包括了4个很好的例子： 1.具有多个坐标轴的GUI，主要学习控制哪一个坐标轴是绘图命令的对象和用编辑文本框读入输入的数。 2.列表框目录阅读器，主要学习获取路径，加载，打开文件 3.从列表框中存取工作区变量，学习把存在于基本工作区的变量名放进列表框，选择多项等 4.地址簿阅读器，这个比较综合，用得技术也比较多。包括打开，保存，修改mat文件，利用handles结构保存和重新调用共享数据。(matlab gui, including four very good example: 1. with multiple axes of GUI, the main learning control which axis is the object of drawing commands and edit the text boxes with the number of read input. 2. The list box directory reader, the main study to obtain the path, load, open the file 3. From the variable list box to access the work area, learning the basic work area exists in the variable names into the list box, select a number of other 4 . address book readers, the more integrated, more technology used. Including open, save, modify mat file, save and re-use handles structure called shared data.)

Code for denoising images. This code differs from standard wavelet denoising techniques in that it uses non-orthogonal wavelets, and unlike existing techniques, ensures that phase information is preserved in the image. Phase information is of crucial importance to human visual perception. Also, this code does have an effective way of determining threshold levels automatically. (Code for denoising images.

本软件是伯南克提出时变的因子扩展VAR模型，能够考察变量间的冲击效应，及其结构变化特征，克服通常VAR的变量少等缺陷。(This software is the factor Bernanke proposed changing the extended VAR model, to study impact effect among the variables, and structural changes, less often overcome VAR variable defects.)
