都市供求信息网分为前、后台两部分设计，前台主要实现信息的显示、搜索与发布功能，其中信息的显示包括列表显示与详细内容显示，而列表显示，又分为首页信息列表显示、查看某类别下所有信息的列表显示和搜索结果列表显示；搜索功能主要包括定位搜索和模糊搜索。后台主要实现的功能为信息显示、信息审核、信息删除、付费设置与退出登录，其中的信息显示功能也分为列表显示与详细内容显示。(Supply and demand information network before the city divided into two parts design background, foreground main achievement of the display, search and publishing of information, which displays information including a list of displays and display details, but the list is displayed, the information is divided into the Home display list, see Under a category displays a list of all the information and the search results list displays Search functions include positioning search and fuzzy search. The main function of the background information display, information auditing, information deleted, pay setting and exit the registry, which is also divided into the information display function displays detailed contents list display.)

这个函数返回n点2dw波段的傅里叶变换的DFT样本序列。通常情况下，以插值点的方式进行放大。(This function returns N point DFT samples of 2dw band of Fourier transform of a sequence. Typically, fft() returns N samples of Fourier transform ranging from 0 to 2pi. This function takes the N-point DFT samples and returns N-point samples corresponding to frequency band wc-dw to wc+dw.)

说明：  关于数字水印的一些代码 基于离散余弦变换 (on digital watermarking code based on the Discrete Cosine Transform)

说明：  本文主要是通过Buck变换器推导出移相全桥变换器的小信号电路模型，接着用MATLAB软件进行仿 真，来判断系统的稳定性。 ( This paper is mainly through the Buck converter is deduced the whole bridge converter phase shifting small signal circuit model, then the MATLAB software to copy True, to judge the stability of the system.)

matlab实现流行识别，用于多相流的测量(matlab to achieve popular recognition for the measurement of multiphase flow)

模拟巴特沃斯滤波器，并可观察期幅频相频特性曲线(Analog Butterworth filter, and can observe the phase frequency of amplitude-frequency characteristic curve)

采用meanshift算法，对小目标进行跟踪，并在多种背景条件下对算法进行验证(Meanshift algorithm used for small target tracking, and in a variety of background conditions to verify the algorithm)

continues analysis of discrete signal, not integer shifting of a discrete signal

说明：  使用矢量控制的一个风力发电系统框图，整个模型是一套完整的系统，能很好的进行仿真，是本人的毕业设计，希望对做这方面的同学有所帮助。(Use of vector control block diagram of a wind power system, the model is a complete system that can simulate good is my graduation project, want to do this help the students.)
