This is my 2 nd year project - work flow engine, implemented to manage the emplyment at company.

说明：  mcm-美国2007年数学建模大赛的题目，我们的想法非常独到新颖，已经有论文发表(mcm-American in 2007 the subject of mathematical modeling contest, and our thoughts are very unique new papers have been published)

用于文本语义分析的潜在语义分析算法LSA(Latent Semantic Analysis)，包含详细的函数说明，原理分析及数据。相比原来版本的LSA，增加了文件demo.m以增加可视化效果，更有利于读者使用。(-Semantic Analysis for Text of Latent Semantic Analysis Algorithm LSA (Latent Semantic Analysis), contains a detailed description, principles of function analysis and data. Run demo.m can see the visualization effect.)

本代码是基于质量弹簧振动系统的BODE图生成的代码 (The code to generate a bode plot of the transfer function of mass-spring system)

Matlab 视频去隔行代码AMCC法，效果很好(Matlab code Deinterlacing)

基于simulink建立的轮胎魔术公式模型（pac2002），可以直接连接其他车辆动力学模块(magic tire model built by simulink，which can be connected with other module of full vheicle dynamics model)

EEMD算法，集合经验模态分解，时域分解程序。按频率进行信号分解，精度高，(EEMD algorithms, time domain decomposition process. According to the frequency signal decomposition, high precision)

说明：  修正MUSIC算法实现相干信号源的DOA估计算法(amendment MUSIC algorithm coherent signal source DOA estimation algorithm)

M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.
