用matlab实现了2dpca算法，基于ORL人脸数据库，识别率较高(Matlab achieved with 2dpca algorithm, based on the ORL face database, the higher recognition rate)

MUSIC算法[1]是一种基于矩阵特征空间分解的方法。从几何角度讲，信号处理的观测空间可以分解为信号子空间和噪声子空间，显然这两个空间是正交的。信号子空间由阵列接收到的数据协方差矩阵中与信号对应的特征向量组成，噪声子空间则由协方差矩阵中所有最小特征值（噪声方差）对应的特征向量组成。(MUSIC algorithm [1] is a feature space based on matrix decomposition method. From the geometric point of view, the signal processing can be decomposed observation space the signal subspace and the noise subspace, it is clear that the two spaces are orthogonal. Signal Subspace data received by the array covariance matrix and eigenvectors corresponding to the signal component, the noise subspace from the covariance matrix of all the smallest eigenvalue (noise variance) eigenvector components.)

关于MATLAB生成正弦波的程序这个是最原始的程序。。。(About MATLAB to generate the sine wave procedures are the most primitive procedures. . .)

Alamoti algorithm!!!

说明：  基于matlab,对图片嵌入水印而不被人感知(Based on matlab, embedded watermark on the image and not be perceived)

svm的回归预测分析，包含源代码和数据，测试可用(svm regression analysis to predict, including source code and data, test available)

本算法是基于图论的广度优先搜索算法，对于配电网的孤岛搜索，以及各个孤岛的电气连通性判别具有很好的效果。(Used to solve the problem about graph search algorithm. )

i hope its useful for students
