利用关联规则发对市场篮子的数据进行挖掘，对同一交易购买的物品的可能性进行了分析。(Association rules are a simple but very useful form of data mining that describe the probabilistic co-occurrence of certain events within a database. They were originally designed to analyse market-basket data, in which the likelihood of items being purchased together within the same transaction were analysed.)

matlab仿真精华，关于三相异步电机的多个案例，很有用(the matlab simulation essence, multiple cases of the three-phase asynchronous motors, useful)

QAM constellation with noise and channel(QAM constellation)

说明：  this is the matlab code for AM signal

关于光流法的一个外文论文，很好的讲述了光流法算法(An optical flow method on foreign language papers, very good about the optical flow algorithm)

产生雷达巴克码（Barker）信号，码内线性调频（LPM）。 RD_wave_mix.m 产生Baker码信号函数 test_wave_mix 测试函数(The Barker code (Baker code) radar signal, linear frequency modulation (LPM). RD_wave_mix.m Baker generated code signal function test_wave_mix test function)

说明：  使用卡尔曼滤波器对信号进行滤波，不局限于工频干扰的频率，简单方便(Kalman filter using the signal filtering, frequency interference is not limited to frequency, simple)

用于进行特征选择的方法，可以对数据进行降维，减少冗余。(For the method of feature selection, the data can be reduced and redundant.)

可以用此代码信号实现频谱仿真，希望对大家有用(You can use this code to achieve spectrum signal simulation, we hope to be useful)
