QPSK Modulation Demodulation, BER vs SNR plot

说明：  假如数据中有N 个变量，而我们想抽取的样本的数量是M,那么在对数据进行抽样的时候，这种方法首先会把N个变量的设计空间均匀的划分开为M份，然后在每个划分好的区域中随机的抽取一点，最后，从这M个变量里，随机挑选之前选好的点，构成我们的样本(If there are n variables in the data, and the number of samples we want to extract is m, then when sampling the data, this method will first divide the design space of n variables into M parts evenly, and then randomly extract a point in each divided area. Finally, from the m variables, randomly select the previously selected points to form our sample)

说明：  人工神经网络MATLAB源程序:此MATLAB程序用于人工神经网络(ANN MATLAB source : This MATLAB procedures for artificial neural network)

The package contains matlab coding and algorithms which will be easy to understand and provides a variety of strategies to develop a good programming skill

vmd源程序的修改版，看起来没那么费尽，更容易懂。(vmd source of the modified version, does not look so racked and easier to understand.)

PSCAD 中调用MATLAB进行计算或仿真 例程(PSCAD call MATLAB for calculation or simulation routines)

matlab课程编程【谷速软件】4RRR平行平面机械臂 (matlab programming courses [software] 4RRR Valley speed parallel plane manipulator)

说明：  卡尔曼滤波，matlab代码 能够直接跑(Kalman filter, matlab code can be run directly)

expectation maximization

k-means示例，用以聚类,里面包含一个特征提取函数，读者可以自行修改(the example of k-means,it will be used clustered.)
