Cluster data for image processing

rbf RBF网络用于建模 ，过程很适合初学者懂的。很详细，很容易的！(RBF RBF network used for modeling, process is suitable for beginners understand. Very detailed, easy! )

利用ar建模 计算ar参数的阶数和ar参数的系数 可以对语音建模(ar modeling)

how implement a codec using matlab Simulation

风机和光伏联合仿真，与电网并联运行，含有线路参数并且设置完整，有光伏并网逆变器和风机并网逆变器(United fan and photovoltaic simulation, running parallel with the grid, containing the line parameters and settings complete with photovoltaic grid inverters and fan grid inverter)

采用点门限玻尔兹曼机实现对图像的自动特征提取以及特征选择。(Point-wise gated boltzmann machine was adopted to realize automatic feature extraction and feature selection of images.)

几个有关通信系统的matlab程序,有关信号，包含：a,对抽样频率为90kHz的信号进行下抽样抗混叠滤波器设计的程序，b,信号抽样率转换的程序，c,通过补零内插对信号进行下抽样，分析抽样对信号频谱的影响的程序(Some matlab programs about communiction system,mainly about signal,a,program about filter to signal sampling without aliasing ,b,transfering signal sampling rate,c,zeros-added sampling,with its influence of phase-frequency。)

水印抗攻击：由高斯正态分布序列 g1 产生 36×4 的水印信号 w0，w0 由(0,1)组成。(Watermark against attacks: from the Gaussian normal distribution generate 36 × 4 series g1 watermark signal w0, w0 from (0,1) component.)

这个程序实现了一个mini的MAC系统，唯一的缺点是并没有考虑到功率限制的问题。(This program realise a system of minipac,the only shortcoming is that the lack consideration of power constraint.)

说明：  一个matlab程序,是一条分形线函数的动态绘制,对数学分形编程有很大启发作用.(a Matlab procedure is a fractal function of the dynamic line drawing, right fractal mathematical programming with inspirational role.)
