说明：  直流马达数学模型，包括三个不同的模型文件，以及相应的PID速度控制、位置控制的Matlab 演示文件(DC motor mathematical model, including the three different models of documents, and the corresponding PID speed control, position control of the Matlab demo files)

灵敏度分析源程序，可用于结构模型修正，但仅运用了自振频率信息，没有运用振型信息(Sensitivity analysis of source code, can be used for structural model updating, but only the use of natural frequency information, there is no information on the use of modal)

在风力发电的模拟系统中,风速模拟是一个重要的环节,正确的风速模型不仅能够很好的 反应实际风速变化情况,而且能够给风力发电系统研究提供正确的源参数。本文用 Matlab/Simulink建立了风速组合数学模型,该模型将风速分为基本风速、阵风、渐变风速和噪声风 速4部分,仿真结果表明该模型能够理想的反应实际风速 (Wind speed simulation is an important part in the simulation of wind power generation system, wind speed model can well reflect the actual wind speed changes, but also to provide the correct source parameters to the wind power system studies. Wind speed combination of mathematical model using Matlab/Simulink, the model will be divided into basic wind speed, gust, gradient, wind speed and noise wind wind simulation results show that the model can be the ideal response to the actual wind)

This is a 16 qam simulink file which can show the scatter plot. useful for students.

介绍了先进PID控制的各种算法的matlab仿真(Introduction of advanced PID control algorithms of matlab simulation)

基于matlab对图像进行中值滤波处理处理，另外附有自己编写的两种中值滤波算法，同时也可以使用matlab自带的median函数(median filter for image processing)

在SENSE成像中如何将中间图像转化为最终图像，就要用到这个程序(Using specfied sampling vector to generate a 2D aliasing matrix. The sampling vector is a vector of n-entries of either 0 or 1, where 0 indicates no k-space line acquisition and 1 indicates k-space line is acquired in the accelerated scan. For example, a sampling vector of [0 1 0 1 0 1 0 1 0 1] indicate the 2-fold acceleration with 8 phase encoding lines. The aliasing matrix is calculated based on Fourier imaging)

The Canny Edge Detector is implemented in MATLAB without using the functions of the image processing toolbox.
