对二维图像进行离散傅里叶变换，分别给出了直流分量移动到频谱中心前后的频谱图样。(Two-dimensional images of the discrete Fourier transform, respectively, given the spectrum to move to the DC component of the spectrum before and after the design center.)

image processing and key generation etc

This matlab code gives the BER of MRC, EGC and SC for QPSK

m序列产生m序列产生m序列产生m序列产生m序列产生m序列产生(m-sequence generator m sequence generation m-sequence generator m-sequence generator m sequence generation m-sequence generator)

基于matlab编程的车辆燃油经济性计算包括图像的绘制等等(the simulation of fuel consumption of the vehicle)

许多系统包含了流量问题。例如交通系统有车流量，金融系统有现金流，控制系统有信息流等。许多流问题主要是确定这类系统网络所能承受的最大流量以及如何达到这个最大流量。MATLAB环境下解决最大流问题(Many systems contain a flow problem. Traffic such as traffic system, the financial system has cash flow, information flow control system. Many flow problem is to determine the maximum flow of such systems and how the network can bear to achieve this maximum flow. Maximum flow problem solving MATLAB environment)
