基于matlab的通断键控调制模块，跟通信原理书上的2ask调制原理类似，在调用时，需要在主函数中加入调制信号，和进制数，一般是2(Matlab on-off keying modulation of the module, with the Communication Theory book 2ask similar modulation principle, in the call, there is a need to add in the main function of modulation signal, and the hexadecimal number, typically 2)

产生雷达发射信号，相位编码采用巴克码，画出其调制信号的时域图和频谱图(barker code of radar . draw the graphic in time domain. draw the graphic in frequency domain.)

说明：  惯性导航的Matlab程序，可以直接运行(Inertial navigation of Matlab procedures, can be directly run)

CMOS集成电路基础知识，CMOS集成电路的接口电路，CMOS集成电路使用注意事项 (Basic knowledge of CMOS CMOS integrated circuit, integrated circuit interface circuit, CMOS integrated circuit use matters needing attention )

说明：  一篇关于异步电机滑模变结构直接转矩控制的硕士论文(a paper of induction motor based on sliding mode DTC )

应用MATLAB编写的二维时域有限差分程序。是初学FDTD的好帮手。建议初学者参考。(Application of MATLAB to prepare two-dimensional finite difference time domain procedure. FDTD are learning a good helper. Recommended reference for beginners.)

说明：   M-file for Project 1 on line parameters and circuit models in Chapter 3 m1.m determines the RLC parameters of the line from its physical description and then computes the ABCD matrix and the circuit parameters of the series RL, nominal pi and equivalent pi model of the line. It computes and plot the receiving-end real and reactive power circle diagram of the line assuming that the voltage magnitude at the sending- and receiving-end are kept constant.

说明：  多项式相加简单程序，欢迎大家评价~~~~~(Add a simple polynomial procedure, welcome to evaluate ~~~~~)
