实现十进制负数求二进制的补码，方便广大学者实现视频或图像加解密过程中用到异或加密(Seeking to achieve a negative decimal binary complement, facilitate the realization of the majority of scholars, video or images used in encryption and decryption process XOR encryption)

（1） 自行设计产生两个离散序列信号，对其进行相加、乘及卷积运算。 （2） 利用filter命令求下面LTI系统的冲激响应： y(n)－0.7y(n－1)－0.6y(n－2) + y(n－3) = x(n) + 0.5x(n－1) （3） 画出系统的零极点图，判断系统的稳定性、因果性。 （4） 绘出系统的频响曲线。(lisan time signal analyse )

说明：  pid控制，模糊控制，模糊pid控制的simulink仿真，三种控制方法的比较.(PID control, fuzzy control, fuzzy PID control, Simulink simulation of fuzzy PID control, comparison of three control methods.)

此文章主要是基于matlab的通信仿真分析。(This article is based mainly on the communication matlab simulation analysis.)

3d金属波导TE、TM模式计算及模拟作图(3d metal waveguide TE, TM mode calculation and simulation mapping)

网上大多数matlab代码跑出来的结果不准确，在原有基础上改了一下，但只能在证据之间不产生冲突情况下使用(Most of the MATLAB codes on the Internet run out of inaccurate results. They have been modified on the original basis, but can only be used in cases where there is no conflict between the evidences.)
