The beginning of a winter break near Spring Festival is always the beginning of a peak period of transportation. If you have ever tried to get a train ticket at that time, you must have witnessed the endless queues in front of every ticket box window

程序源码是对心电信号进行R 峰检测，等电位位线的检测等，能快速高效完成计算-The program source is the ECG R-peak detection, detection of potential bit line can be done quickly and efficiently calculate the

Tompkins algorithm input : ecg data, sampling frequency output : R-peak sample point

对心电信号进行R波波峰的寻找，输入原始心电信号，输出为波峰时间点和值(Search for R wave peak of ECG signal)

波达方向（DOA）估计的基本问题就是确定同时处在空间某一区域内多个感兴趣的信号的空间位置（即多个信号到达阵列参考阵元的方向角）。最早的也是最经典的超分辨DOA估计方法是著名的MUSIC方法，MUSIC是多重信号分类（Multiple Signal Classification）的英文缩写。它是由R．O． Schmidt于1979年提出来的，由1986年重新发表的。MUSIC算法利用了信号子空间和噪声子空间的正交性，构造空间谱函数，通过谱峰搜索，检测信号的DOA．(The basic proble
