利用MATLAB GUI设计实现图像处理的图形用户界面，利用MATLAB图像处理工具箱实现以下的图像处理功能： 1. 采用matlab Guide设计实现图像界面与按钮界面。 2. 连接摄像头，编写MATLAB初始化程序 3. 用摄像头采集一副图像，并能实现保存（使用控件按钮保存）。 4. 设计按钮实现对图像进行任意的亮度和对比度变化调整，显示和对比度变化前后的图像。 5. 设计按钮实现用户能够用鼠标选取图像感兴趣区域，显示和保存该选择区域。 (Designed and implemented using MATLAB GUI graphical user interface, image processing, using MATLAB image processing toolbox of image processing functions to achieve the following: 1. Designed to achieve an image using matlab Guide button interface with the interface. 2 Connect the camera to write MATLAB initialization procedure 3, with the camera capture an image and save to achieve (using the control button to save). 4 Design button on the image to achieve any change in the brightness and contrast adjustment, display, and contrast changes before and after images. 5 button design to achieve the user to select an image region of interest with the mouse, display and save the selected area.)

两个向量的内积，外积，正交的实现以及可视化，matlab例程，可实现向量的内积，外积，以及正交的可视化(Inner product of two vectors, outer product, orthogonal realization and visualization, matlab routines, enabling vector inner product, outer product, and orthogonal visualization)

周期高斯一介导、高斯二介导即高斯脉冲（即UWB信号）的功率谱图像，对应不同的占空比和不同的脉冲形式，随着阶数的增加中心频率右移，频谱也为高斯形式，且随着周期数增多，呈现线谱形式(Cycle Gaussian ordinary derivative, ie the Gaussian two-mediated Gaussian pulse (the UWB signal) of the power spectrum image, corresponding to different pulse duty cycle and a different form, with the increase of the order of the center frequency shifted to the right, the spectrum also Gaussian form, and with the number of cycles increased, showing the form of line spectrum)

多输入多输／出(MIMO)雷达具有多个发射天线阵元和多个接收天线阵元，每个 阵元发射不同的信号且发射信号相互正交。(Multiple-input multiple input/output (MIMO) radar has multiple transmit antenna elements and multiple receive antenna elements, each element emission signal and transmit signals orthogonal to each other.)

本课题主要研究当信道中的加性噪声为高斯白噪声时，对接收端数字信号的判决带来的影响。 通过实验的手段分析信道无噪声的情况时，对接收端译码译码带来的影响；通过实验的手段分析信道有噪声的情况时，对接收端译码译码带来的影响； 代码可直接运行，包括基带下的误码率仿真，频带下的仿真，以及相互间的对比。界面很好(Signal in channel transfer process, not only by the channel itself, it brought, also influenced by the additive noise, Gaussian white noise is a communication channel additive noise. The main subject of study when the additive channel noise is white Gaussian noise, the impact of digital signal on the receiving end of judgment. By means of analysis of the experimental channel without noise, the impact on the receiving end decoding decoding noisy channel decoder decoding on the receiving end, the impact by means of analysis of the experiment )

非常有用的matlab 程序例子，三维球面程序！！(It is very usefull to draw a ball.)
