考察例1 4 - 8中的1 4个点。A中的最近点对为(b,h)，其距离约为0 . 3 1 6。B中最近点对为 (f, j)，其距离为0 . 3，因此= 0 . 3。当考察 是否存在第三类点时，除d, g, i, l, m 以外 的点均被淘汰，因为它们距分割线x= 1的 距离≥ 。RA ={d, i, m}，RB= {g, l}，由 于d 和m 的比较区中没有点，只需考察i 即可。i 的比较区中仅含点l。计算i 和l 的距离，发现它小于，因此(i, l) 是最近

Verilog HDL: Magnitude For a vector (a,b), the magnitude representation is the following: A common approach to implementing these arithmetic functions is to use the Coordinate Rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine, magnitude, and phase using an iterative process. It is made up of a series of micro-rotations of the vector by a set of predetermined constants, which are powers of two. Using binary arithmetic, this algorithm essentially replaces multipliers with shift and add operations. In a Stratix™ device, it is possible to calculate some of these arithmetic functions directly, without having to implement the CORDIC algorithm.

design LP,HP,B S digital Butterworth and Chebyshev filter. All array has been specified internally,so user only need to input f1,f2,f3,f4,fs(in hz), alpha1,alpha2(in db) and iband (to specify the type of to design). This program output hk(z)=bk(z)/ak(z),k=1,2,..., ksection and the freq.

About: hamsterdb is a database engine written in ANSI C. It supports a B+Tree index structure, uses memory mapped I/O (if available), supports cursors, and can create in-memory databases. Release focus: Major feature enhancements Changes: This release comes with many changes and new features. It can manage multiple databases in one file. A new flag (HAM_LOCK_EXCLUSIVE) places an exclusive lock on the file. hamsterdb was ported to Windows CE, and the Solution file for Visual Studio 2005 now supports builds for x64. Several minor bugs were fixed, performance was improved, and small API changes occurred. Pre-built libraries for Windows (32-bit and 64-bit) are available for download. Author: cruppstahl

Floyd-Warshall算法描述 1)适用范围： a)APSP(All Pairs Shortest Paths) b)稠密图效果最佳 c)边权可正可负 2)算法描述： a)初始化：dis[u,v]=w[u,v] b)For k:=1 to n For i:=1 to n For j:=1 to n If dis[i,j]>dis[i,k]+dis[k,j] Then Dis[I,j]:=dis[I,k]+dis[k,j] c)算法结束：dis即为所有点对的最短路径矩阵 3)算法小结：此算法简单有效，由于三重循环结构紧凑，对于稠密图，效率要高于执行|V|次Dijkstra算法。时间复杂度O(n^3)。 考虑下列变形：如(I,j)∈E则dis[I,j]初始为1,else初始为0，这样的Floyd算法最后的最短路径矩阵即成为一个判断I,j是否有通路的矩阵。更简单的，我们可以把dis设成boolean类型，则每次可以用“dis[I,j]:=dis[I,j]or(dis[I,k]and dis[k,j])”来代替算法描述中的蓝色部分，可以更直观地得到I,j的连通情况。

5.22④ 假设系数矩阵A和B均以三元组表作为存储结构。 试写出满足以下条件的矩阵相加的算法：假设三元组表A 的空间足够大，将矩阵B加到矩阵A上，不增加A、B之外 的附加空间，你的算法能否达到O(m+n)的时间复杂度?其 中m和n分别为A、B矩阵中非零元的数目。
