三相PWM逆变器，采用双闭环控制，内环电流，外环电压~~~~(Three-phase PWM Inverter with Double Closed Loop Control)

说明：  这是一个计算镜头视场的软件，非常简单但是很实用。(This is a calculation of the lens field of view of the software, very simple but very practical.)

线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号，此时由于多普勒效应，信号的频率发生偏移，这个源码仿真出雷达检测到目标距离信息的回波信号。(LFM signal is a commonly used electromagnetic radar signal, when the radar signal detection to the target time, after reflection of radar echo signal, at this time due to Doppler effect, the signal)

说明：  史上最详细的matlab教程，涵盖了matlab使用的各个方面，很有帮助作用(The history of the most detailed tutorial matlab, covering all aspects of the use of matlab, helpful role in)
