Project - Data Handling and Interpolation

OPEN THE SCRIPT FILE :

clc

d= xlsread('expriment_data.xlsx');

v = d(:,1);

i = d(:,2);

plot(v,i,'--');

xlabel('v volt');

ylabel('i amp');

v1=[-17.3;0.1;0.9];

i1=interp1(v,i1,v1);

hold;

plot(v1,i1,'r');

we run the command the plot will be shown on the top

i2=interp1(v,i,v2);

plot(v2,i2);

the interpolation range fron the excel sheet we plot this figure
