Googlecode较有代表性得完整代码，可以按照自己需要组合使用。(Google code is more representative and complete code, which can be combined according to its own needs.)

基于Simulink/Matlab的同步发电机模型。应用状态空间方程组等，从原理出发搭建，而非直接使用Simulink中已有的模型。(Based on Simulink/Matlab synchronous generator model. Application of state-space equations, etc., starting from the principle of construction, rather than directly using the existing model in Simulink.)

excel中利用vba合并多个sheet的简单代码，请注意修改 和to的序号范围(using a simple code in vba excel merge multiple sheet, note and to modify the serial number the range)

说明：  气象要素文件（hdf）读取详细说明，适合MATLAB初学者借鉴(Meteorological element file (hdf) read details)

说明：  2. 关于无线信道的多普勒谱，请回答以下问题： (1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请描述产生混叠的各种原因； (2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理； (3) 请用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请描述：自己用计算机产生的经典谱是正确的依据。(2. Regarding the doppler spectrum of the wireless channel, please answer the following questions: (1) in some wireless channels, doppler frequency shift will cause aliasing of the output signals of the wireless channel.Describe the various causes of aliasing; (2) there is a classic spectrum in the doppler spectrum in the wireless channel, please explain the mechanism of producing this spectrum shape; (3) please use Simulink tool to write code (s-function mode) to generate a single-path Rayleigh channel, whose doppler spectrum is the classical spectrum, in which the moving rate is 120km/h.And please describe: your own computer generated classical spectrum is the correct basis.)
