说明：  本程序实现对多进制PSK数字调制系统的仿真。程序运行需要几分钟，请耐心等待(this program right M-ary PSK modulation system simulation. Procedures required for the operation of a few minutes, please wait patiently)

8 band kp method calculate the valence band structure, using finite difference method

经典图像算法书Deblurring Images: Matrices, Spectra, and Filtering里面用到的程序 (Classic image algorithms book Deblurring Images: Matrices, Spectra, and Filtering )

说明：  图像的几种锐化处理，包括sobel算子，roberts梯度法和laplace算子锐化。并且将四种图像放在一起形成对比。(Several image sharpening, including sobel operator, roberts gradient and laplace operator sharpening. And will contrast the four images together.)

LSI就是这样一种维数约减方法。它可以通过对“文档向量矩阵”进行解奇异值分解（SVD: Singular Value Decomposition）运算，自动计算得到一个比原始空间小得多的有效语义空间(LSI is such a dimensionality reduction method. It can be through the "document vector matrix" for the singular value decomposition (SVD: Singular Value Decomposition) operation, automatically calculated an effective semantic space is much smaller than the original space)

用MATLAB内含的随机数生成器生成所需的随机量，是进行概率模拟编程的参考工具(Included with the MATLAB random number generator to generate the required random quantity is the probability of a reference tool for simulation programming)
