用MATLAB实现“商人怎样安全过河”模型求解(Using MATLAB to solve“how to secure traders to cross the river” model )

可以用来求复合半导体能带随着偏压的变化情况，可以考虑到interface charges(Can be used for compound semiconductor energy band changes with the bias, you can take into account the interface charges)

说明：  下面的程序是求多项式y=x^6-10x^5-26x^4+344x^3+193x^2-1846x-1680在区间[-8,8]的最小值，误差不超过0.001。对于这个复杂的多项式，可先用matlab绘制函数的大概曲线，确认函数的最小值大概处于[-8,8]之间，再用本程序求出精确解。 (The following procedure is a polynomial y = x ^ 6-10x ^ 5-26x ^ 4+344 x ^ 3+193 x ^ 2-1846x-1680 in the interval [-8,8] of the minimum error is not more than 0.001. This is a complex polynomial, can first draw function with matlab about curves, to confirm the function of the minimum are probably in [-8,8] range, and then find the exact solution of this program.)

说明：  独立分量分析代码（matlab编写）有很强的试用价值(Independent Component Analysis code (matlab preparation) has a very strong trial value)

cdma系统matlab仿真，在两个用户的背景下采用了直接扩频码实现扩频解扩，bpsk调制解调，程序已经运行过，没有问题！(cdma system matlab simulation, in the context of two users using a direct spread spectrum spreading codes realize despreading, bpsk modem, the program has been run before, no problem!)

包括matlab程序,c,vc++原代码和一些全景图拼接论文资料(This is the open source Hugin panorama stitching software source code from svn down under)

gui设计,在开发各类软件之前可以帮助人们设计软件，并展示设计效果，更好的促进软件研制.(GUI design ，can help you to design GUI,and may help you to show what you will do,so It is more usful to you!)

Side impact accidents against a tree or pole remainthe most dangerous accident scenarios in rally cars. Statistical data shows that 52 of the fatalities between 2004 and 2009 concern crashes against a rigid pole by the track sides, whilst among those more than 60 were side impacts. Despite the present scientific efforts, rallying cars side impacts are still among the least understood primarily due to limited space between the occupant and door sill, evolving safety regulations and vehicle dynamics.

该程序用一个实例进行演示线性回归方程的建立。(The procedures used to establish an instance demonstrates the linear regression equation.)

这是求信噪比的程序，就是信息噪声功率比上噪声功率(This is the signal to noise ratio for the procedure is, the information on the noise power ratio noise power)
