Sigma_delta

说明：  这是国外一本经典教材附带的程序，通信系统的matlab实现，所含例子丰富(This is a classic foreign materials attached to the procedures, communications systems to achieve matlab contains abundant examples of)

PSO_DynamicEnvironment是用粒子群算法（particle swarm algorithm）解决动态环境寻优（最优值不断变化）的问题。文件打开后运行PSO_DynamicEnvironment.m文件即可得到结果，代码中有详细注释，方便修改。运行示例已经保存为图片附在压缩包中。(PSO_DynamicEnvironment solve dynamic environment particle swarm optimization algorithm (particle swarm algorithm) (optimal value changing) problems. Run PSO_DynamicEnvironment.m file to get the file to open the result, the code has detailed notes, easy to modify. Run the sample has been saved as a picture attached to the compressed package.)

this contains pdf file to learn more about the lyapunov exponent & bifurcation diagram of the chaotic system.

k-mean算法，使用matlab工具箱工具对图像进行聚类分割。(k-mean algorithm, using matlab clustering toolbox tool for image segmentation.)

分数阶傅里叶变换资料,非常有用的信号处理变换工具(Document of chirp Flouier，which is very useful for signal processing and transformation.)

是对于是128*128灰度图片的压缩MATLAB代码,希望有人会有用(For 28* 123 gray image compression MATLAB code, hope someone will be useful for)

在matlab绘图中可设置函数曲线图视角的用户界面的m函数。(Drawing in matlab function to set the curve of the user interface perspective m function.)

说明：  对图像进行均值化，并用均值化后的图进行数字全息的模拟，同时运用两种不同方法进行全息图的再现(The mean of the image and use the mean of digital holographic map after the simulation, while using two different methods of reproduction of the hologram)

说明：  单相并网逆变器，使用无源阻尼，实现并网电流波形和电网电压波形同频同相(Single-phase grid-connected inverters, using passive damping, realize grid-connected current waveform and grid voltage waveform in the same frequency and phase)

说明：  一个用matlab软件做的抽取滤波器的程序，在软件中打开文件仿真后得到6个波形(Software used to do a decimation filter matlab program, open the file in the software simulation waveforms obtained 6)
