Project - Data Handling and Interpolation

ANSWER

AIM :In a laboratory experiment, data of voltage and current has been recorded and the same is attached in an excel file ( Click on this link VI.xlsx ). Read the excel file in the Matlab program and perform the interpolation in the range of -17.3:0.1:0.9. Generate the interactive plot for the interpolated data and store them in a text file.

TO FIND :

• Find missing data and save it in text
• Interpolate the data set
• Save your program and attach the same.
• Save txt file and upload in attachment

SOLUTION :

PROGRAME :

clc

close all

d=xlsread('VI.xlsx');

v=d(:,1);

i=d(:,2);

xq = -17.3:0.1:0.9;

vq= interp1(v,i,xq);

plot(v,i,'*',xq,vq,':')

xlabel('volt')

ylabel('mAmp')

title('V&I')

legend('V&I','xq&vq','location','southeast')

writematrix(vq,'V&Ioutput.txt');

RESULT :
