说明：  线性实不变系统的各种傅里叶变换，z变换的分析与演示。适用于离散时间信号处理领域。(The same system of linear real Fourier transform, z transform analysis and presentation. For discrete-time signal processing.)

使读者能对matlab快速上手和熟练掌握操作和应用(Matlab so that readers can quickly get started and master the operation and application)

MIT-BIH心电数据库中包含有大量的心电信号，用户可以直接下载这些信号用于信号分析，算法验证等。但是其数据存储格式复杂，只能用其提供的工具包进行读取，很不方便。本源码可以直接读取MIT-BIH中的format212和format16格式的心电数据，免去了学习其繁琐工具包的过程。(MIT-BIH ECG database contains a large number of ECG signals, users can directly download these signals used in signal analysis, verification algorithm. However, the complexity of its data storage format, can only provide a toolkit to read, very inconvenient. The source can be directly read the MIT-BIH in format212 and format16 ECG data format, which eliminates the cumbersome tool kit to learn their process.)
