extern的用法，本文较详细的介绍了extern的用法及注意事项。(extern usage, this paper describes in detail the usage of extern and precautions.)

熵（近似熵，样本熵）,适合初学者。值得一看。。。。。(Entropy (entropy of approximate entropy, sample), suitable for beginners. Worth a look... )

这个资料为数字图像处理技术方面matlab的入门资料，讲述了matlab的数字图像处理工具包的使用，以及基本的图像处理函数.(This information technologies for digital image processing matlab introductory information about the digital image processing matlab toolkit to use, and basic image processing functions.)

用Matlab对图像、声音信号在时域及频域进行分析及其应用(如小波变换及其应用等)，将近100个源代码含。(many analyising methods and its application of iamge and audio signal processing in time and frequency domain,such as wavelet and it s application, including approximately 100 source codes.)

用simulink中的SimMechanics模块搭建两关节机械臂模型，并用S-function函数编写控制程序，采用的是计算力矩法跟踪参考信号。(SimMechanics module structures in simulink model of two-joint robot arm, and write control program, a function of the S-function is computed torque method tracks the reference signal.)

说明：  此程序给出由三个不同频率的正弦所组成信号的联合时－频分布。该图是三维图形的二维投影，在该图中，一个轴是时间，一个轴是频率。由该图可清楚地看出信号的时间－频率关系。(This program shows three different frequency sinusoidal signal composed of joint time- frequency distribution. The plan is two-dimensional projection three-dimensional graphics in the figure, one axis is time, an axis is frequency. By the diagram is clear that the signal of the time- frequency relation.)

通过蒙特卡罗仿真说明直接序列扩频系统在抑制正弦干扰的有效性(Monte Carlo simulation shows direct sequence spread spectrum system in the sinusoidal interference inhibited the effectiveness)

scalar quantization of image and communication over erassure channel and error removal

Excel Link is a software add-in that integrates Microsoft Excel and MATLAB in a Microsoft Windows-based computing environment. By connecting Excel and MATLAB, you can access the numerical, computational, and graphical power of MATLAB from Excel worksheet and macro programming tools. Excel Link lets you exchange and synchronize data between the two environments.
