在matlab平台下产生信号序列通过QPSK方式调制通过高斯信道以及瑞利信道，对其中的过程的信号时域以及其频谱，星座图情况进行分析(Matlab platform in the signal sequence generated by the QPSK modulated by the Gaussian channel and Rayleigh channel, which processes the signal for time-domain and its spectrum, constellation analysis of the situation)

一个经典的关于光流法的运动图像目标检测 已调试成功(Moving image target detection of optical flow method is a classic has been successful commissioning)

this code is for the pegasis algorithm in the wireless sensor networks.

文档里面有详尽的Matlab绘图命令介绍，较为好用。。。(A document,which has a detailed description of Matlab drawing commands, is really useful. . .)

Keyboard-controlled interactive power spectrum demonstrator, useful for teaching and learning about the power spectra of different types of signals and the effect of signal duration and sampling rate. Single keystrokes allow you to select the type of signal (12 different signals included), the total duration of the signal, the sampling rate, and the global variables f1 and f2 which are used in different ways in the different signals. When the Enter key is pressed, the signal (y) is sent to the Windows WAVE audio device. Press K to see a list of all the keyboard commands. T. C. O Haver

建立cost231仿真模型函数，cost231是一种无线信道(Cost231 simulation model-building function, cost231 is a wireless channel)

a GOOD BOOK FOR CIVIL ENGINEERING

its about Dc machine and can use for other kind of machine

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.)

基于Hough变换检测圆的matlab程序，很实用的，可拿来直接用(Based on Hough transform circle detection matlab program, very practical, can be used directly)
