对水印图像进行置乱，然后嵌入到载体图像小波域中的细节子带中(the watermark image is Scrambled, and then embedded into the details of wavelet sub-band domain)

有12个外表一模一样的小球，其中有一个的质量和其他11个球不一样（11个球的质量完全相同） 而且该球不知道是轻点还是重点。现在给你一个天平（无砝码），只有3次测量机会，请你找出该球。(12 looks exactly the same ball, which has a quality and not the same as the other 11 balls (11 balls in the quality of the identical) and that the ball does not know the point or focus light. Now to give you a balance (no weight), only 3 measurements chance, you find the ball.)

This program plots spectrograms (vertical slices of intensities versus frequencies, with slices plotted against time).

掷骰子x，相同的骰子如果大于Y，得分为零，否则为个点数和。多次掷骰子观察概率情况(Dice x, the same dice if greater than Y, score zero points and one otherwise. Probability of observing multiple dice)

说明：  Market Newman写的复杂网络的加权GN算法 算法用Python写的 其基本思想是不断的删除网络中具有相对于所有源节点的最大的边介数(ege betweenness)的边，然后，再重新计算网络中剩余的边的相对于所有源节点的边介数(The basic idea is to delete the network with respect to all of the source nodes of the largest betweenness (EGE betweenness) edges, then re computing network the remaining edge relative to the boundary of the source node number of all)

function g=nonlineareq(x) Here is an example of nonlinear system that can be solved by using the Matlab command "fsolve" written in the file called "solution.m" (see quasi-Newton or Levenberg-Marquardt methods). g(1)=x(1)-4*x(1)*x(1)-x(1)*x(2) g(2)=2*x(2)-x(2)*x(2)+3*x(1)*x(2)
