飞行器航迹模拟程序，利用matlab进行仿真(matlab trace)

This code performs likelihood ratio test (LRT) for VAR model to determine optimal lag length, constant term is automatically included. Test is performed on contiguous lags, thus DOF=neqn^2*1. Guido Travaglini, 06.15.2011

遗传算法优化神经网络程序[matlab]，十分有用(the generic algorithm of the network ,it is very helpful)

有限元求解结构固有频率和振型、显示（中心差分法，Newmark法）、隐式法、非线性法程序(middle difference/Newmark/nonlinear)

数字图像隐藏技术的仿真，针对一个图片现将其转换为灰白图像，然后将要隐藏的图片加入样本中，加入椒盐噪声攻击，最后将图片还原。(Digital image information hiding technology simulation, for a picture now converted to gray image, will then be hidden image is added to the sample, adding salt and pepper noise attack, finally will restore the picture.)

本程序主要采取结构体进行编程，对帧中运动车辆进行跟踪，一个车一个标号，标号自增1.(The main structure of this program is programmed to take on the frame to track moving vehicles, a car of a label, label increment 1.)

说明：  基于HSM（harmonic-to-subharmonic）的基音提取算法。本算法通过对HSM建模，消除了基音提取过程中基音减半或增倍的现象，大大提高了准确性能。(Based on HSM (harmonic-to-subharmonic) of the pitch extraction algorithm. HSM model by the algorithm, the extraction process to eliminate the pitch halving or pitch doubling phenomenon, greatly improving the accuracy of performance.)
