下面是我编的一个软硬阈值去噪的matlab程序 下面是我编的一个软硬阈值去噪的matlab程序：thr=sigma*(2*lgN)1/2/lg(j+1) 用[x,xn]=wnoise(2,10,6) 产生噪声测试数据-The following is Part I of a of hard and soft threshold denoising matlab procedure is the following hardware and software, I made a threshold denoising matlab program: thr = sigma* (2* lgN) 1/2/lg (j+1) by [x, xn] = wnoise (2,10,6) noise test data(thr=sigma*(2*lgN)1/2/lg(j+1) 用[x,xn]=wnoise(2,10,6) 产生噪声测试数据-The following is Part I of a of hard and soft threshold denoising matlab procedure is the following hardware and software, I made a threshold denoising matlab program: thr = sigma* (2* lgN) 1/2/lg (j+1) by [x, xn] = wnoise (2,10,6) noise test data)

利用离散余弦变换DCT和小波变换DWT实现对图片的变化域压缩并进行仿真以及性能分析(Using the discrete cosine transform DCT and wavelet transform DWT realization of the picture changes and simulated field compression and performance analysis)

产生脉内Frank相位编码调制信号，并对其进行平方、四次方变换，利用四次方FFT结果为单频信号的特点完成调制识别，最后绘图观察其瞬时相位曲线。(Generating pulse code modulation signal within Frank polyphase, and its square, four square transformed by FFT results for the fourth power single-frequency signal modulation characteristics of complete identification, finally drawing to observe the instantaneous phase of the curve.)

无线传感器网络分簇路由算法，很经典的，适合初学者练习使用(Clustering routing algorithms in wireless sensor networks, very classic, suitable for beginners to use )

lorez指数是混沌时间序列中的很重要的性能指标，(lorez index is a chaotic time series of the very important performance indicators,)

power_seriesbranch,功率电子领域matlab仿真文件，已经验证过，程序运行正常( power_seriesbranch,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

Mobile Robot Model + Code + Docs in Matlab

利用白噪声序列和传递函数生成有色噪声的源代码，很实用(Using white noise sequence and colored noise transfer function to generate source code, very useful)

matlab弹奏歌曲生日快乐~ 这里是生日快乐钢琴版~之前编了个生日快乐，是对照网上那个坑爹的最炫民族风编的，效果就像打击乐器（因为只有一个波形）真是不忍心吐槽了。 这个是钢琴完美版的，还带和弦呢！就是用两行不同的旋律同时弹，相当于钢琴用两只爪弹。（喂，你确定那是叫和弦么拍飞） 因为我不会乐器并且五音不全，所有简谱的知识都来自小学音乐课orz，所以或许跑调也…也…… 哼，你要是敢说我跑调，那你到我面前来把这首歌唱一遍来证明你不是跑调的！！一般唱歌都会跑调，编个程跑调又肿么了！跑调才萌嘛 你们喜欢哪首歌也可以把简谱写在指定位置（我在编码中有标注），我把所有的音符的函数都补全了！！现在是所有歌曲无压力！！！ 当然，这个程序不是我全部原创的，是参考了网上已有的程序又改造以及补充了一下。 把下面的代码复制到M文件就可以播放生日快乐了~(matlab playing the song Happy Birthday ~)

在群体进化若干代后,将弱解空间删除,在以后的进化进程中以同样的群体大小只在强解空间进行群体的繁殖,则可加大强解空间的个体密度,提高解的精度,这样有助于性能优良的个体的产生,(After several generations of evolution in the population, a weak solution space removed in the future evolution of the process with the same population size in a strong solution space only breeding colony, it can increase the density of strong individual solution space, to improve the accuracy of the solution, This helps produce good performance of individuals,)
