数字水印在matlab下的ＤＷＴ仿真实现整个程序运行还行，共享给大家-jpeg of the Matlab Simulation, and the whole process has run OK, for everyone to share (Digital Watermarking in DWT under matlab simulation run also realize the entire process line, to share to everyone-jpeg of the Matlab Simulation, and the whole process has run OK, for everyone to share)

实现基于SVM的说话人识别，其算法比传统的svm有所改进，鲁棒性更强(SVM-based speaker recognition, and improvements in the algorithm than the traditional svm more robust)

To Calculate the Spectral efficiency of a continuous-time AWGN Channel in bits/s/Hz

Calculate the eigenvalues of many 3x3 real symmetric matrices.(Calculate the eigenvalues of many 3x3 real symmetric matrices. Computation is non-iterative, based on fully vectorized matlab matrix operations, and GPU computation is supported. It is fast and efficient for processing a number of 3-by-3 matrices at once. This code particularly suits tensor/Riemannian calculus in 3D, visualization/analysis of volumetric tensor images, image Jacobian/Hessian analysis, stress/tensile strength computation on tensor fields, three dimensional diffusion processes, determining the rotation axes of a motion field, etc....)
