  • 实验一:三次样条插值(P56

    实验一:三次样条插值(P56,例6) 一、实验目的: 1) 掌握三次样条插值的运用 2) 了解拉格朗日插值在高次上的误差 二、实验环境:Matlab6.5 三、实验内容: 1) 给定函数f(x)=1/(1+x2),-5<=x<=5,节点xk=-5+k,(k=0,1,2…10),用三次样条插值求S10(x),S10’(-5)=f’(-5),S10’(5)=f’(5)。 2)作原函数f(x),拉格朗日插值函数Ln(x),三次样条差值函数Sn(x)。画出三个函数的图像,比较它们的区别。

  • Input : A set S of planar points Output : A convex hull for S Step 1: If S contains no more than f

    Input : A set S of planar points Output : A convex hull for S Step 1: If S contains no more than five points, use exhaustive searching to find the convex hull and return. Step 2: Find a median line perpendicular to the X-axis which divides S into SL and SR SL lies to the left of SR . Step 3: Recursively construct convex hulls for SL and SR. Denote these convex hulls by Hull(SL) and Hull(SR) respectively. Step 4: Apply the merging procedure to merge Hull(SL) and Hull(SR) together to form a convex hull. Time complexity: T(n) = 2T(n/2) + O(n) = O(n log n)

  • documentation for optimal filtering toolbox for mathematical software package Matlab. The methods i

    documentation for optimal filtering toolbox for mathematical software package Matlab. The methods in the toolbox include Kalman filter, extended Kalman filter and unscented Kalman filter for discrete time state space models. Also included in the toolbox are the Rauch-Tung-Striebel and Forward-Backward smoother counter-parts for each filter, which can be used to smooth the previous state estimates, after obtaining new measurements. The usage and function of each method are illustrated with five demonstrations problems. 1

  • 算法思路:   1.如果只有一个金片

    算法思路:   1.如果只有一个金片,则把该金片从源移动到目标棒,结束。   2.如果有n个金片,则把前n-1个金片移动到辅助的棒,然后把自己移动到目标棒,最后再把前n-1个移动到目标棒.   3.单纯对于有N个金片要挪动的步数求出, 可以使用递推方法,满足递推方程f(i) = f(i - 1) * 2 + 1

  • 通过socket编程

    通过socket编程,编写两个独立运行的C++程序,一个为服务器,一个是客户端。 本次作业能实现客户端对服务器的下载文件和上载文件的操作。 客户端:D盘的FTP文件夹存放要上传的文件,F盘的FTP文件夹存放下载的文件。 服务器端:D盘的FTP文件夹存放供用户下载的文件,F盘的FTP文件夹存放用户上载的文件。
