Project - Data Handling and Interpolation

Ans:

Here we have used the command 'interp1' for interpolation. The output xq1 is put to the text file called 'interpolation'.

Code for interpolation:

clear

clc

T = readtable("VI.XLSX");

x= T.Current;

y=T.Volt;

xq = -17.3:0.1:0.9;

xq1 = interp1(y,x,xq);

fileID = fopen('interpolation.txt','w'); % Open the text file to write the output

fprintf(fileID,'%f','xq1'); % print the output xq1 to the text file

figure(1);

plot(x,y,'o',xq,xq1,':'); % plotting the interpolation

grid;
