K均值聚类算法，网上已存在很多，我是新手，大神的看不懂，觉得自己编的比较适合菜鸟理解吧。。。(K-means clustering algorithm)

esh generation is one of the most critical aspects of engineering simulation. Too many cells may result in long solver runs, and too few may lead to inaccurate results. ANSYS Meshing technology provides a means to balance these requirements and obtain the right mesh for each simulation in the most automated way possible. ANSYS Meshing technology has been built on the strengths of stand-alone, class-leading meshing tools. The strongest aspects of these separate tools have been brought together in a single environment to produce some of the most powerful meshing available.

抑制载波单边带simulink程序，进行频谱计算研究，分析信号特征。(Sideband suppressed carrier simulink program, Calculation of spectral analysis of the signal characteristics.)

主要是利用simulink对三相全桥电路的功率因数校正电路，其中三相全桥采用SVPWM(The power factor correction circuit of three phase full bridge circuit is mainly based on Simulink, in which the three-phase full bridge is SVPWM.)

说明：  国外牛人写的串口代码，好东西大家分享，强力推荐(Foreign cattle were written serial code, good things to share with you, highly recommended)

Modulation test for OFDM : This is a set of five (5) codes about COFDM (Coded Orthogonal Frequency Division Multiplexing) and coding schemes such as Convolutional, BCH, Reed Solomon (RS) and Low Density Parity Check (LDPC). The study uses an OFDM signal over an AWGN Channel with white Gaussian noise model, and calculate the Bit Error Rate wich is plotted.
