在matlab环境下实现了对MPSK通信系统的仿真，(mpsk)

一本很不错的MATLAB 工具箱使用的书籍,是清晰的文本pdf格式, 希望大家喜欢 (A very good book to use MATLAB toolbox, is a clear text pdf format, hope you like)

The disparity map forms the basis of many computer vision techniques. A disparity map is effectively a limited 3D model

说明：  （1）应用9×9的窗口对上述图象进行随机抽样，共抽样200块子图象； （2）将所有子图象按列相接变成一个81维的行向量； （3）对所有200个行向量进行KL变换，求出其对应的协方差矩阵的特征向量和特征值，按降序排列特征值以及所对应的特征向量； （4）选择前40个最大特征值所对应的特征向量作为主元，将原图象块向这40个特征向量上投影，所获得的投影系数就是这个子块的特征向量。 （5）求出所有子块的特征向量。 ((1) the application of 9 × 9 window of these images at random, a total sample of 200 sub-image (2) all sub-images according to out-phase into a 81-dimensional row vector (3) all 200 lines for KL transform vector, derived its corresponding covariance matrix of eigenvectors and eigenvalues, in descending order by eigenvalue and the corresponding eigenvector (4) a choice to 40 corresponding to the largest eigenvalue eigenvector as the PCA, the original image block to the 40 feature vectors on the projection, the projection coefficients obtained by this sub-block eigenvector. (5) calculated for all sub-block eigenvector.)

采样率转换程序，程序主体分为上采样与下采样(Sample rate conversion process, the program is divided into the main sampling and down-sampling)

In this program we demonstrate the MP, OMP, WMP, and Thresh algorithm, by running them on a set of test signals and checking wether they provide the desired outcome
