可以分别介绍MFA，又名边界Fisher分析。对模式识别十分重要的作用，可以帮助新手更好的理解KNN原理，对人脸识别有着很好的演示作用。-Can introduce MFA respectively, also known as boundary Fisher analysis. For pattern recognition is an important role, can help beginners a better understanding of KNN principle, has

matlab环境下 em算法处理心电信号的代码，很有参考价值-Matlab environment EM algorithm to deal with the code of the ECG signal, there is a reference value

DFA->NFA->MFA 并依次输出数据表(DFA->NFA->MFA And output the data table in turn)
