改变AVI视频文件的分辨率，并自动生成改变大小后的avi文件(change the size of avi file, and automatically generate a avi file that have been resized.)

希望大家一起学习 MATLAB图像图像处理 相关知识(Hope that we are learning MATLAB image image processing knowledge)

基于Matlab的异步电机的起动、控制、调速等的仿真(asynchronous motor matlab simulink)

码分多址，是在无线通讯上使用的技术，CDMA 允许所有的使用者同时使用全部频带(1.2288Mhz)的系统仿真(CDMA is used in wireless communications technology, CDMA allows all users to simultaneously use all bands (1.2288Mhz) System Simulation)

该程序代码能对地震数据波谱进行小波分析。(The program code of the seismic data spectral wavelet analysis.)

matlab实现Preisach模型，画出Everett函数以及Preisach平面(- approximate measured hysteresis loops - simulate arbitrary minor hysteresis loops - plot the Preisach function, the Everett function, the reversible component)

说明：  小波分析的经典案例，很适合初学者学习。。。。。(Wavelet analysis of the classic case, very suitable for beginners to learn)

说明：  本程序是暂态稳定分析程序，3机9节点模型，对其在pt时刻7号节点发生三相短路故障，并在ct时刻将故障切除进行仿真，最后绘出2号和1号发电机的功角差与时间的关系曲线。发电机模型采用三阶模型，忽略阻尼，电枢电阻取为零；励磁系统仅有量测和放大环节，忽略反馈和电压调节器；负荷采用恒定阻抗负荷。(This program is a transient stability analysis program, three machine nine node model, which has three-phase short circuit fault on node 7 at Pt time, and cut off the fault at CT time for simulation, and finally draw the relationship curve between power angle difference and time of generator 2 and 1. The generator model adopts the third-order model, neglecting the damping and taking the armature resistance as zero; the excitation system only has the measurement and amplification links, neglecting the feedback and voltage regulator; the load adopts the constant impedance load.)

Matlab连续系统灰色PID跟踪，预测加控制(Matlab for Gray PID tracking system, add the control prediction)

this is the code to apply hilbert transform on a signal.
