对两条心电信号波形数据存储转换成的text文本进行分析，找出这两条心电信号之间的最小DTW(动态规整)距离，用于在心电信号数据库中对样本信号进行匹配，找出相隔距离最小的模版信号，判断样本信号所属种类。-Of the two ECG waveform data stored in the text into text analysis to identify between the two ECG minimum DTW (dynamic warping) distance, for the EC

此程序用经验模态方法，将心电信号分解成多个IMF，并对信号做时频分析，观察信号中所含有的频率。-This procedure using empirical mode method, the ECG signal is divided into a number of IMF, and the signal time-frequency analysis, observation signal containing frequency.
