多自由度有阻尼系统的MATLAB求解代码，输入刚度，阻尼，平衡方程，自动计算结构阻尼频率和振型。(The MATLAB solution code of the damping system with multiple degrees of freedom is used to enter the stiffness, damping and equilibrium equations, and the damping frequency and vibration mode of the structure are automatically calculated.)

用来计算地球表面两点之间的距离，该程序通过输入两点的经纬度坐标确定两点的距离，可用于各种工程应用当中(The Earth s surface used to calculate the distance between two points, two points in the program by entering the latitude and longitude coordinates to determine the distance between two points can be used in a variety of engineering applications which)

Speaker recognition is the task of validating individual s identity using invariant features extracted from their voices print. Speaker recognition technology common applications include authentication, surveillance and forensic applications. This Paper investigates the performance of three automatic model selections based on Gaussian Mixture Model (GMM). These approaches are Bayesian information criterion (BIC), Bayesian Ying–Yang harmony empirical learning criterion (BYY-HEC) and Bayesian Ying–Yang harmony data smoothing learning criterion (BYY-HDS). Experimental evaluation of these methods is presented.
