用matlab生成无标度网络，并对无标度网络进行分析(Using matlab to generate scale-free networks, and scale-free network analysis)

matlab wavelet code, 小波变换的matlab源代码(matlab wavelet code)

ddd Coastal Land Use/Land Cover maps and Coastal Regulation Zone map on 1:25,000 and 1:50,000 scales derived from satellite data were collected from State Coastal Zone Management Authorities and enlarged into 1:12,500 scale. The georeferenced maps were digitized in ARC-INFO GIS. Digitized maps were edited, labeled and a layout was prepared. The area statistics of different Ecologically Important Areas were generated and presented in the maps.

一篇2007年全国数学建模竞赛的获奖论文，可以用来参考人口预测问题的写作。(A 2007 National Mathematical Contest in Modeling award-winning paper, can be used to refer to the population projections writing.)

DFT谱分析，加矩形窗与加hamming窗对比(DFT spectrum analysis, plus rectangular window hamming window contrast)

各种使用simulink纯滞后系统仿真实例(Various simulation simulink delay system)

说明：  噪声中正弦信号的现代法谱分析，采用了直接法、间接法、Bartlett法和Welch法，分别分析了不同窗长度、不同窗函数和不同信噪比对谱估计的影响。(Modern normal spectrum analysis of sinusoidal signal in noise adopts direct method, indirect method, Bartlett method and Welch method. The effects of different window lengths, different window functions and different signal-to-noise ratios on spectrum estimation are analyzed respectively.)
