改变AVI视频文件的分辨率，并自动生成改变大小后的avi文件(change the size of avi file, and automatically generate a avi file that have been resized.)

这个文件是，opendss与matlab交互编程的标准示例，可以帮助学习者更快的掌握opendss与matlab的交互(This file is a standard example opendss interact with matlab programming, can help learners to quickly grasp the interaction with the matlab opendss)

用于转子故障振动，采集信号后，用小波包方法对振动信号进行频谱分析，比傅立叶变换更细化。(Spectrum analysis of vibration signal by wavelet packet method)

SAR 回波仿真及成像处理，包括RDA 算法仿真、RMA 算法仿真、CSA 算法仿真(SAR echo simulation and imaging processing, including RDA algorithm simulation, RMA algorithm simulation, CSA algorithm simulation)

智能天线技术，里面介绍了很多关于频域宽带波束形成方面的算法。作者L.C Godara是这方面的大牛，发表了很多关于波束形成方面的paper，大家可以参阅一下。(Smart antenna technology, which introduces a number of algorithms on the frequency domain broadband beamforming aspects. The Author LC Godara large cattle in this area, published a paper about the many aspects of beam forming, we can see it.)

matlab tool box 3.3 about image acquisition

The random walker algorithm was introduced in the paper: Leo Grady and Gareth Funka-Lea, "Multi-Label Image Segmentation for Medical Applications Based on Graph-Theoretic Electrical Potentials", in Proceedings of the 8th ECCV04, Workshop on Computer Vision Approaches to Medical Image Analysis and Mathematical Methods in Biomedical Image Analysis, p. 230-245, May 15th, 2004, Prague, Czech Republic, Springer-Verlag.

该文件被用于人工数据集的测试。这些数据都是随机生成的。在百度中也可以搜索到相关内容。数据集名字为ultwotwo(this file can used for Performance Comparison on Artificial Data)

其实popupwindow用起来比Dialog 方便，因为dialog一切都需要你自己来实现，而popupwindow帮我们实现了很多，我认为在使用的时候关键我们要看清参数： popupWindow.showAtLocation(parent, gravity, x, y) parent这个是一个父view试图， gravity 这个默认是居中，我们要指定显示方式：Gravity.LEFT | Gravity.TOP 最后两个参数就是显示的坐标位置，这样就可以根据需求自己定位显示位置了
