说明：  该程序主要用于将UFF格式的文件转换成matlab的mat格式文件。(it can change the uff file to the mat filte which is used to store the data in matlab.)

使用matlab画圆，对图傅里叶变化，零频移中，反变换实验(test fft and ifft)

有关MATLAB的图像绘制功能的ppt,很方便，很实用的(The MATLAB' s image rendering capabilities of the ppt, very convenient and very practical)

阵列信号处理中常用的一些算法，包括MUSIC,ESPRIT,AR等(Array signal processing algorithms, including MUSIC, ESPRIT, AR)

LCL型滤波并网逆变器双环控制参数设计与优化，对工程实践的指导作用明显(LCL type filter and inverter loop control parameter design and optimization, the guiding role of engineering practice significantly)

说明：  基于三电平整流器matlab建模仿真原型，双闭环控制策略。可以借鉴参考(Based on the MATLAB modeling and Simulation prototype of three-level rectifier, the double closed-loop control strategy is proposed. It can be used for reference.)

说明：  信号处理卷积计算，开发环境是MATLAB.(Convolution signal processing terms, the development environment is MATLAB.)

space time coding is used in MIMO systems to exploit diversity or improve error ot transmission rate

k-d树的matlab程序，包含了KDTREE, KDTREEIDX and KDRANGEQUERY functions。提供了两个Demo scripts(kdtree_demo.m & kdrange_demo.m),很实用( This distribution contains the KDTREE, KDTREEIDX and KDRANGEQUERY functions. Included are the source code files in kdtree/src, as well as precompiled mex files for the following systems: - Mac OS X (Matlab 6.5) - Redhat Linux (Matlab 6.5) - Windows (Matlab 6.1) Two demo scripts are provided (kdtree_demo.m & kdrange_demo.m). The new features added June 2004: + You can now use N dimensional data points, where N>3. + Use KDTREEIND to return the index value to the closest point, instead of the closest point values. + KDRANGEQUERY can now return these index values as well.

在土工三轴试验中应用该方法使得试样的变形测量更加简便。通过使用高精度标定板，对该数字图像测量方 法进行了精度分析，结果表明亚像素角点检测方法的轴向和径向测量的标准差都达到了0．02个像素，相对测量精度达到10‘4 数量级。(Triaxial tests in application of this method makes it easier specimen deformation measurements. By using high-precision calibration board, the digital image analysis to measure the accuracy of the method, the results of the standard deviation to measure the axial and radial table Minya pixel corner detection methods have reached 0.02 pixels, relative measurement accuracy of 10 ' 4 magnitude.)
