Posted by Eko Budiarto on April 19, 2011

Tentukan akar pangkat tiga dari 3,5 berdasarkan data dibawah ini :

x \sqrt[3]x
0 0
1 1
2  1.25992
3 1.44224
4  1.58740
5 1.70997
6    1.81712
7   1.91293

jawab

x =[0,1,2,3,4,5,6,7];

y =[0,1,1.25992,1.44224,1.58740,1.70997,1.81712,1.91293];

xi =0:0.5:10;

yi = interp1(x,y,xi, ‘cubic’);

plot (x,y,’o’,xi,yi)

jadi interpolasi akar pangkat tiga dari 3,5 adalah

x =[0,1,2,3,4,5,6,7];

y =[0,1,1.25992,1.44224,1.58740,1.70997,1.81712,1.91293];

xi =3.5:0.5:3.5;

yi = interp1(x,y,xi, ‘cubic’)

yi = 1.5184
