可在系统引导时工作的RootKit,较简单 1) It s very small.The basic framework is just about 100 lines of assembly code.It supports 2000,XP,2003 2) It patches the kernel at runtime(no files are patched on disk).(basic version has this code removed , so as other

4QAM 常模de 算法,算法简单明了，运行正确-4QAM norm de algorithm

运用matla编写的一个小游戏界面，能够对矩阵进行LU分解，希望读者能从中得到启发-Your goal is to use LUGUI to compute the LU decompositions of nine matrices with as little roundoff error as possible. Your score for each hole is norm(R,inf)+norm(Leps,inf)+norm(Ueps,inf) where R = L*
