Common Spatail Pattern. EEG signal processin

计算常用指标Gmean,F-score,sensitivity,specificity,precision,roc和auc曲线，输入test_label,predict_label两个列向量，即可获得以上指标(calculate some indexes)

说明：  通信系统的仿真,Reed-Solomon-codes是纠错码的一种,可以用于通信领域,本例子给出了基于matlab的程序,可用于实际的仿真!(communications system simulation, Reed-Solomon-codes is an error-correcting codes, communications can be used, the example is given of the procedures based on Matlab can be used for actual simulation!)

这是非线性方程（组）的数值解法，里面的源程序都经matlab2008测试通过了！！(This is a non-linear equation (group) of numerical solution, which have been the source of the matlab2008 test! !)

说明：  MATLAB程序，用于dsp编程软件仿真，信号的产生，fft变换(MATLABghdsp)

基于matlab的潮流计算，可实现人机界面交互。显示潮流的结果(Matlab calculation based on the trend, enabling human-machine interface interaction. Shows the trend of the results)
