FDTD仿真喇叭天线，能观察得到其电场在自由空间随时间的分布情况。(FDTD method is a time domain analysis.Here we first we design a wave-guide and there after we just increase its broad side.Our aim is to this simulation is plotting its electric field response with time and how will it response in outside free space. Here we just take 170 time steps one who can interested in antenna designing they can also plot the radiation pattern of this HORN antenna.Just take the field in the outside the mouth of HORN antenna and there do the simple formula to near filed far field transfer and measure it at your band of antenna.Best of LUCK all of you.)

Simulation of m/m/1/k type queuing process

振动信号预处理，主要为五点三次平滑法和平均法(Vibration signal pre-processing, mainly for the 5.3 second smoothing method and average method)

一种实现复矩阵的SVD分解的算法，使用Matlab进行仿真，亲测可用。(SVD decomposition algorithm to achieve complex matrix, using Matlab to simulate pro-test is available.)

matlab fft matlab fft hit (matlab fft hit matlab fft hit )

MATLAB与c++混编的案例代码，可运行，是学习的好例子(MATLAB and c++ mixed case code can be run, is a good example of learning)

matlab图像图像处理，利用移位进行灰度值的变化，达到减小灰度值的效果(the matlab image change of image processing, by using shift grayscale value, to achieve the effect of reducing grayscale value)

F16的气动数据，以及进行matlab和simulink联合仿真的F16飞行品质和飞行性能计算程序(Aerodynamic data of F16 and a program for calculating the flight quality and performance of F16 using MATLAB and Simulink)

说明：  这是一个对比仿真实验： 基于复信号构造系统，生成IQ数据，进行QAM复调制，然后进行复解调，给出调制前后的频谱： 之后在用传统的载波调制的方式重新在做一遍，给出调制前后的频谱(This is a comparative simulation experiment: Based on complex signal construction system, IQ data is generated, QAM complex modulation is carried out, then complex demodulation is carried out, give the spectrum before and after modulation After that, the traditional carrier modulation method is used to do it again, give the spectrum before and after modulation)
