FDFD方法计算双脊波导的特征模以及场分布，对计算电磁学的学习很有帮助(FDFD Method to calculate the eigenmodes and electromagnetic field distribution of double ridge waveguide,it will be very helpful for the study of computational electromagnetics)

说明：  例程，用于功能测试。如程序有错请大家指出.(Routine for function testing. If there is any mistake in the procedure, please point out)

该代码首先对ECG信号进行消噪过滤，并且对信号进行平方，加窗等处理，最后用于对QRS波形的检测，压缩文件内同时包含了2个心电数据信号，可直接用于测试(The code first ECG signal de-noising filter, and the square of the signal, such as window handle, and finally used for the detection of QRS waveform, at the same time compressed file contains two ECG data signals can be directly used to test)

matlab要求编写函数，并画出图的matlab习题，供大家参考(prepared Matlab functions, and draws a plan of Matlab Exercise, for your reference! !)
