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.

可以求解系统的亚谐波共振,例如求解轧机振动系统的1/3亚谐波共振(You can solve the sub-harmonic resonance system)

该程序用matlab编写数值积分方法，包括梯形公式，Simpson公式和Romberg算法，在main.m文件测试三类算法。这是数值计算方法是必须掌握的代码。(The program is prepared using matlab numerical integration methods, including trapezoidal formula, Simpson and Romberg algorithm for three kinds of formulas in main.m file for testing. Is the numerical calculation method must master code.)

使用风电场历史数据，基于pso-bp算法进行风电功率点预测(PSO-BP algorithm for prediction of wind power)

一个遗传算法编的程序,大家看看吧.有人说不能用,但我用的很好.(a genetic algorithm of Procedure, we look at it. Some people say you can not use it, but I use very good.)

where M is a model object (IDMODEL, IDPOLY, IDSS, IDFRD, or IDGREY). MAG is the magnitude of the response and PHASE is the phase (in degrees). W is the vector of frequencies for which the response is computed. These can be specified by [MAG,PHASE,W] = BODERESP(M,W). The frequency unit is angular frequency (rad/s or rad/M.TimeUnit). Only frequencies up to the Nyquist frequency are considered.
