说明：  1.1 背包问题 有一个徒步旅行者，已知他能承受的旅行背包的重量不超过a（kg）。设有n种物品可供他选择装入背包，这n种物品分别编号为1，2，…，n。其中第i种物品每件的重量为ai（kg），其使用价值（指一件第i种物品对旅行者来说所带来的好处的一种数量指标）为ci（i＝1，2，…，n）。问这位旅行者应如何选择携带这n种物品的件数，使得总价值最大？ (1.1 knapsack problem is a hikers. he is known to travel to withstand the weight of the backpack not exceed a (kg). N Species with articles for his choice loaded backpack, n product were numbered 1, 2, ..., n. I first of which product each ai of the weight (kg), its value (i refers to a section of the types of items travelers the benefits brought by a number of indicators) for the ci (i = 1, 2, ..., n). Asked how travelers who choose to bring this product to the n pieces, making the total value of the largest?)

利用matlab解方程的程序，可以用过微分方程，提供了集中方法(Using matlab solving equations can be used to differential equations, provides methods)

数据拟合程序 用2次多项式 ax^2+bx+c 拟合给定的数据（最小二乘解）(Data fitting procedure)

对数据进行傅立叶分析，从时域转换到频域，观察信号的频谱结构，从分析信号的特点(Fourier analysis of the data, the time domain to the frequency domain, spectral structures of the observed signal, the signal characteristics the analysis)

这是有关matlab的编程，值得一看，呵呵呵呵呵呵呵呵(matlab)

Program to use your camera as a scanner. Automatically detects the page on the picture. (Description Useful program if you don t have a scanner or need to scan quickly a lot of pages. It detects the page on the picture, make it rectangular, cut the borders and enhance the contrast. Function parameters are the input picture filename and output filename. Some parameters that can be changed are described in the function. Be careful with the flash of the camera, it creates a non-homogeneous luminosity difficult to clean. Required Products Image Processing Toolbox MATLAB release MATLAB 7.5 (R2007b) )

4阶龙格库塔，定义法计算rossler系统lyapunov指数，结果比较精确！(4-order Runge-Kutta, defined method rossler system lyapunov index results more precise!)
