说明：  根据采样定理编写程序,实现模拟信号的采样,画出采样波形.(According to sampling theorem, programming, analog signal sampling, draw sample waveform.)

本程序根据训练好的网络文件ANN.mat预测新的数据文件，得到均方误差，并画出预测数据和原数据的对比图。(the procedures under the trained network file ANN.mat anticipating new data files, to be mean-square error. and the mapping out of the original forecast data and the map data comparison.)

说明：  用matlab画单个点，多个点电荷的电场线和等势面(Drawing electric field lines and equipotential surfaces of single point and multiple point charges with MATLAB)

应用背景2012年由Kostinger提出的KISSME度量方法，从统计推断学的角度来考虑问题，最终表示成马氏度量学习的表达方式，从而得到马氏度量矩阵参数的估算方式，解决了当前很多度量学习方法在的大数据量下高时间复杂性的问题； 关键技术 马氏度量学习的表达方式，度量矩阵参数的估算方式，概率论，机器学习，人脸识别等技术
