VB高分（拉格朗日插值法）

先看《http://jgjwc.njtu.edu.cn:8080/bjtumcm/course/shuxueshiyan/course/3-5.htm》里的“1．Lagrange插值”，我只要有插值法的三次插值多项式，可分N段插直，例：A=1,1.05,1.1,1.15,1.2,1.25,1.3,1.35,1.4,1.45,1.5,1.55
B=0.635,0.649,0.66,0.671,0.682,0.691,0.7,0.711,0.72,0.726,0.733,0.74
输出三次插值多项式！用QQ：498018194 好用的话再追加150分
X0=1,X1=1.1,X2=1.15,X3=1.2......Y0=.635,Y1=0.649,Y3=0.66......

Answer 1

？？？jdeA=1,1.05,1.1,1.15,1.2,1.25,1.3,1.35,1.4,1.45,1.5,1.55
B=0.635,0.649,0.66,0.671,0.682,0.691,0.7,0.711,0.72,0.726,0.733,0.74

Answer 2

我以前用C语言写过，你要不要？

Answer 3

dimx(4),y(4),l(4)fori=0to3
forj=0to3ifi><jthen
l(i)=l(i)(x-x(j))/(x(i)-x(j)endfork=0to3
L3=l(i)*y(i)end
因只能打120个字不好意

Answer 4

什么是分N段插直？那是不是有n个结果呢？
