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。
(Experiment I: cubic spline interpolation (P56, cases of 6) First, the experiment was: 1) cubic spline interpolation to master the use of 2) understanding of Lagrange interpolation in high-error second, experimental environment: Matlab6 .5 c, experimental elements: 1) a given function f (x) = 1/(1+ x2),-5 <= x <= 5, node xk =- 5+ k, (k = 0,1,2 ... 10), using cubic spline interpolation for S10 (x), S10 (-5) = f (-5), S10 (5) = f (5). 2) for the original function f (x), the Lagrange interpolation function Ln (x), cubic spline difference function Sn (x). Draw the three functions of images, compare the difference between them.)

seepage
SEEP5( Property , Value ,...) creates a new SEEP5 or raises the
existing singleton*. Starting the left, property value pairs are
applied to the GUI before seep5_OpeningFunction gets called. An
unrecognized property name or invalid value makes property application
stop. All inputs are passed to seep5_OpeningFcn via varargin.

说明: 有源电力滤波器(APF:Active power filter)是一种用于动态抑制谐波、补偿无功的新型电力电子装置,它能够对不同大小和频率的谐波进行快速跟踪补偿,之所以称为有源,是相对于无源LC滤波器,只能被动吸收固定频率与大小的谐波而言,APF可以通过采样负载电流并进行各次谐波和无功的分离,控制并主动输出电流的大小、频率和相位,并且快速响应,抵消负载中相应电流,实现了动态跟踪补偿,而且可以既补谐波又补无功和不平衡。(APF:Active power filter))
