MachineLearning Classifican KNN-Based Clustering for Improving Social Recommender Systems

包括：隐藏混沌序列即隐藏参数的生成；对图像进行隐藏；恢复出隐藏前置乱的目标图像；恢复出原目标图像；对隐藏目标置乱处理等(Include: hidden chaotic sequence that is hidden parameter generation images hidden the restoration of a hidden goal of arbitrary pre-image the restoration of the original target image to hide the goal of treatment, such as scrambling)

二维光子晶体的FDTD法，MATLAB 源程序(Two-dimensional photonic crystals FDTD method, MATLAB source code)

It is a novel fuzzy based sleep mode technique for WSN that turns off the ONUs (placed at the customer premises) when certain traffic conditions are verified. The objective is to achieve an improved energy efficiency without impacting too much the Quality of Service perceived by end-users. The whole operation is managed at the central Node and the length of the sleep time periods is computed employing a statistical method.

二维正态分布的检验函数，如果需要进行二维正态分布的检验，在你的程序运行前运行此程序，就可直接调用函数功能。(Dimensional normal distribution test function, if you need a two-dimensional normal distribution test, run your program before you run this program, you can directly call the function function.)

关于LDPC的。是Mackcy网站上的LDPC编译码程序。(On the LDPC. Mackcy site is LDPC coding and decoding procedures.)

列出求素数的程序，所谓素数就是只能被它的自身和1除尽的数(require a prime number)

本资料含有低通/高通带通等matlab程序，程序简短但经典(This information contains a low pass/high pass band-pass and so on matlab program, the program short but classic)

说明：  将数组a[0]~a[size-1] 中重复的字母删除（仅仅保留第一次出现的字母，后续的重复字母均删除）(The array a [0] ~ a [size-1] Remove duplicate letters (just the first time to retain the letters, follow-up letters were removed duplication))
