Electrocardiography (ECG or EKG) is the recording of the electrical activity of the heart over time via skin electrodes. This program make a EKG signal.

说明：  bpsk仿真程序，仿真ber（误码率）等性能(bpsk simulation, emulation ber (bit error rate) and other properties)

里面包括常用的MATLAB 图像函数，十分符合新手(Which include the popular image of MATLAB functions, is in line with novice)

基于学习的图像超分辨率重建，可以进一步了解基于学习的方法。(Learning-based super-resolution image reconstruction, we can further understand the learning-based approach.)

把matlab计算后的数据保存成obj格式的文件，能保存点和点点之间的连接关系，即obj格式的中的v和f(Obj format to save data into files that can save the points and little connection between the relationship that the v in obj format and f)

说明：  对自由落体运动的MATLAB仿真，不考虑空气阻力。(MATLAB simulation of free-falling movement, without considering air resistance.)
