please give me a code for this ieee paper

采用MR阻尼半主动振动控制的matlab仿真程序(THESE ARE MATALB SIMULATIONS FOR STRUCTURAL VIBRATION CONTROL SYSTEM USING MR DAMPER WITH SEMI ACTIVE CONTROL ALGORITHMS.)

提出了一种多迸制频移键控(M娲K)信号调制分类及解调方法，选取截获接收机输出的MFSK信 号的时频脊线作为分类特征，利用无监督聚类算法求取最佳聚类数M．利用时频脊线的Ham：小波变换 估计码元宽度，并且利用对应最佳聚类数的聚类中心确定抽判门限，通过对时频脊线抽样判决，实现了 MFSK信号的解调．理论分析和对实际信号的处理结果证明了此算法的可行性．(new algorithm is proposed for elassillcation and demodulation of MFSK signals．The ridge of time— frequency representation of MFSK signals is analyzed．Modulation elassi_fieation is realized by using the unsupervised clustering algorithm to determine the optimal nulnllt2r of clusters．In order to demodulate MFSK signals，the Haar wavelet transform is used to estimate the code—width and the centers of optimal clusters are used to determine thresholds．Theoretical analysis and practical signal processing results justify the robusticity and the efficiency of the new classification and demodulation Mgorithm．)

本文是一片关于FFT的Matlab仿真分析，很具体，配有大量清晰的仿真图片~~有利于FFT初学者的学习(This article is one of the Matlab simulation on the FFT analysis, very specific, clear配有大量simulation picture ~ ~ is conducive to learning for beginners FFT)

说明：  本程序包括树木、草以及鲜花的加载，花和草可以在风中摆动，这个动态森林很逼真(This procedure, including trees, grass and flowers of the load, flowers and grasses can be swinging in the wind, the dynamics of forest is very realistic)

这是用MATLAB做的三维立体图。。。。。。。。(This is done using MATLAB three-dimensional map. . . . . . . .)

函数mean5_3(五点三次平滑算法)对数据进行平滑处理的源代码 (Function mean5_3 (five-point smoothing algorithm three times) to smooth the data source)

matlab 专业设计 源于课本的原文件 适合于编程人员(matlab professional design textbooks from the original document is suitable for programmers)

It tells you how to make a GA programme!(It is useful for a new learner to leaen GA!)

说明：  一个小波消噪的matlab例子，里面有源程序 希望可以帮到大家(a denoise example of wavelet,)
