【正文】 值函數(shù)。 Cubic spline interpolation 。關(guān)鍵詞:函數(shù);多項式插值;三次樣條插值;曲線擬合;MATLABAbstract:In numerical analysis ,the function value is often calculated .when the function is only given a function point set ,the simple expression of the function is given by the interval .which involves the use of a simple function to approximate the known plex function .in order to solve this problem ,we use polynomial interpolation and cubic spline interpolation tow kind of interpolation method and use MATLAB numerical analysis software to program ,to achieve the curve fitting of the corresponding date to obtain the best cure fitting ,and to choose the best interpolation method to solve the problem of curve fitting to the date. Keyword: Function 。 《數(shù)值分析》課外課堂大作業(yè)論文題目: 基于多項式插值與三次樣條插值曲線擬合的比較姓 名: 學(xué) 號: 學(xué) 院: 專業(yè)方向: 聯(lián)系方式:(號) (手機(jī)號 )導(dǎo)師姓名: 完成人(親筆)簽字 基于多項式插值與三次樣條插值曲線擬合的比較摘要:在數(shù)值計算中經(jīng)常要計算函數(shù),當(dāng)函數(shù)只在有限點集上給定函數(shù)值要包含改點集的區(qū)間上用公式給出函數(shù)的簡單表達(dá)式,這就涉及在已知區(qū)間上用簡單函數(shù)逼近已知復(fù)雜函數(shù)問題。本文為了解決這類問題就采用多項式插值與三次樣條插值兩種插值法
