用matlab打开即可，能能绘制功率谱的函数，十分方便 (Open using matlab can draw power spectral function is very convenient)

matlab的图论工具箱，基本够用了，大家试一试。(matlab toolbox graph theory, basic enough, please try.)

这是永磁同步直线电机的空间矢量控制模型，已经通过仿真请放心下载(This is the space vector control of permanent magnet synchronous linear motor model, the simulation has been downloaded, please be assured)

生成砂轮上磨粒位置及运动轨迹，可以利用其来生成工件表面形貌(The formation of abrasive grain position and motion track on the grinding wheel)

DVB-S2系统仿真代码，需要在2007版以上运行(DVB-S2 system simulation code, required to run at more than 2007)

说明：  基于buck 变换的电源有缘功率因数校正(APFC using matlab )

编写一个matlab函数用一个N点离散傅里叶变换同时计算两个N点实序列的离散傅里 叶变换，并将结果与直接使用两个N点离散傅里叶变换计算出来的结果进行比较(Write a matlab function with an N point discrete Fourier transform and calculate actual sequence of two N point discrete Fourier transform, and the results with the direct use of two N point Discrete Fourier Transform calculated results are compared)

hiding technique by segmentation of image methods in matlab

说明：  模糊c均值（fcm）实现无监督聚类算法，经本人尝试，程序可以正常运行(Fuzzy C-means (FCM) to achieve unsupervised clustering algorithm, I try, the program can run normally)
