this is matlab code for estimating the static linear system with Least Squre that is written by matlab 7.0. Here we want to estimate the below function: 1 - u^2 + 2*u^3 +u^5 +3*u^7 these are 2 files : without noise and with noise finally,there are plots for showing results.

哈弗曼编码解码的MATLAB程序，简单实用(Huffman codec MATLAB program, simple and practical)

说明：  用于图像压缩，并同时对图像进行加密，减少存储空间(In this project we implemented an Image Compression and Encryption algorithm from the reserach paper "Novel Image Compression-encryption hybrid algorithm based on a key-controlled measurement matrix in compressive sensing" by Nanrun Zhou, Aidi Zhang, Fen Zheng, Lihua Gong.)

说明：  图像数字水印的方案毕业论文，基于dct和dwt的算法(Image digital watermarking scheme graduation thesis, based on DCT and DWT algorithm)

matlab实例100个，适合于学习matlab基础学习。其中都是源代码。(matlab example 100, the basis for learning to learn matlab. Which are the source code.)

说明：  MATLAB 环境下的 Alamouti qpsk 仿真，可以运行通过(Alamouti qpsk MATLAB simulation environment, you can run through it)

运行在matlab平台，基于果蝇算法的最小而成支持向量机算法(Running on the MATLAB platform, the minimum support vector machine algorithm is based on the Drosophila algorithm.)

说明：  原理：以待处理的像素作为中心，取一个nXn的模板，在模板中选择k个与待处理像素的值最接近的像素，将这k个像素的均值替换原来的像素值。 假设n=3，k=5，调用方法：b = KNNMeanFilter(a, 3, 5)(Principle: to be treated as the center pixel, take a nXn template select the template and the pending k-nearest pixel values of pixels, this k pixels mean replacing the original pixel value. Assuming n = 3, k = 5, call the method: b = KNNMeanFilter (a, 3, 5))
