MATLAB IMPLEMENTATION OF STAR ALGORITHM

说明：  用MATLAB实现频域平滑滤波以及图像去噪代码6. 计算频率域图像的幅值并进行对数变换，利用’imshow’ 显示频率域图 像； 7. 在频率图像上去除滤波半径以外的数据(置0)； 8. 计算频率域图像的幅值并进行对数变换，利用’imshow’ 显示处理过的 频域图像数据； (6. Calculate the frequency domain image of the amplitude and logarithmic transformation, using imshow show the frequency domain map Like 7. Removal of the image filtering in frequency than the radius of data (set 0) 8. Calculate the frequency domain image of the amplitude and logarithmic transformation, using imshow show-treated Frequency domain image data )

fuzzy preference rough set based feature evaluation and selection

对均匀线性阵列方向图进行仿真，为大家研究mimo雷达或者相控阵雷达方向图提供思路(Simulate the uniform linear array pattern to provide ideas for studying the mimo radar or phased array radar pattern)

说明：  神经网络设计源码，通过MATLAB仿真验证过(Neural network design source, verified by MATLAB)

matlab语言开发的图像去噪的固定点迭代法， 基于偏微分方程的一个算法。(Matlab language Image Denoising fixed-point iteration method, based on partial differential equations of an algorithm.)

MVAcltbern illustrates the (univariate) Central Limit Theorem (CLT). n*1000 sets of n-dimensional Bernoulli samples are generated and used to approximate the distribution of t = sqrt(n)*(mean(x)-mu)/sigma -> N(0,1). The estimated density (blue) of t is shown together with the standard normal (red).
