Infonet一篇经典论文，一种基于虚拟坐标的紧凑路由协议S4的Matlab仿真代码( a classic paper at Infonet, based on the virtual coordinates of compact routing protocol S4, Matlab simulation code)

Step 1: Set i=1 FA=f(a) Step 2: while i≤ No do step 3-6. Step 3 set p=(a+b)/2 FP=f(p) Step 4 if FP<TOL or (b-a)/2<TOL then OUTPUT(p) STOP. Step 5 set i=i+1 Step 6 if FA.FP > 0 then set a=p FA=FP else set b=p. Step 7 OUTPUT (‘Method failed after No iteration,No=’, No) STOP.

2009年9月全国大学生数学建模获奖论文所需程序代码，其中有较详细的matlab编程，应该有些用处吧(September 2009 Mathematical Contest in Modeling program code required for the award-winning paper, including more detailed matlab programming, it should be useful)
