说明：  对心电信号进行预处理，肌电、工频干扰、相位漂移滤除，为后续分析做准备(The ECG signal is preprocessed, and the EMG, power frequency interference and phase drift are filtered out to prepare for the subsequent analysis)

最新的从官方网站下载的LIBSVM工具箱(LIBSVM toolbox downloaded from the official website)

图像处理MATLAB程序（教学使用）-图像灰度级修正（直方图规定化）(MATLAB image processing program (Teaching)- image gray level correction (histogram specification))

说明：  BP神经网络进行数据分类，是一种多层前馈神经网络，该网络的主要特点是信号前向传递，误差反向传播。运用梯度下降法，(BP neural network is a multi-layer feedforward neural network for data classification. Its main characteristics are forward signal transmission and back error propagation. Using gradient descent method and BP neural network to classify data is a multi-layer feedforward neural network. The main characteristics of this network are forward signal transmission and back error propagation. Using gradient descent method,)
