上机作业:多项式插值

上机作业:多项式插值. 1 、教材第 50 页,计算实习题 3 ( 将插值节点改为 1,4,…,81) ,利用这 9 个点做 8 次 Newton 多项式插值 N 8 ( x ) 和分段三次 Hermite 插值函数 H 3 ( x ) ,画出 N 8 ( x ) , H 3 ( x ) 和原函数 ( 平方根 ) 的图像。 ( M 文件取名为 hw21.m )( H 3 ( x ) 选做 ). 提示:不需要给出 N 8 ( x ) 和 H 3 ( x ) 的具体表达式,画图时取 [1, 81] 上的等距离散点,步长取 0.5.

  1. 上机作业:多项式插值 1、教材第 50 页,计算实习题 3 (将插值节点改为 1,4,…,81),利用这 9 个点做 8 次 Newton多项式插值 N8(x) 和分段三次Hermite 插值函数 H3(x) ,画出 N8(x),H3(x) 和原函数(平方根)的图像。(M文件取名为 hw21.m)( H3(x) 选做) 提示:不需要给出 N8(x) 和 H3(x)的具体表达式,画图时取 [1, 81] 上的等距离散点,步长取 0.5 上机要求 • 将所有 M 文件作为附件,发给mhjs@system.mail • 邮件主题为:机号-学号-姓名 • 每个 M文件的第一行为:%机号-学号-姓名
