Project - Data Handling and Interpolation

MAIN PROJECT

Question : 01

answer:

% Read data from Excel file

data = xlsread('C:\Users\DELL\Downloads\VI.xlsx');

voltage = data(:,1);

current = data(:,2);

% Perform interpolation

xq = -17.3:0.1:0.9;

vq = interp1(voltage,current,xq,'linear');

vq2 = interp1(voltage,current,xq,'spline');

% Create interactive plot

figure(1);

plot(voltage,current,xq,vq,'r*');

grid on

legend('Original','Interpolated');

xlabel('Voltage (V)');

ylabel('Current (A)');

figure(2);

plot(voltage,current,xq,vq2,'g*');

grid on

legend('Original','Interpolated');

xlabel('Voltage (V)');

ylabel('Current (A)');

% Store data in text file

dlmwrite('interpolated_data.txt',[xq',vq'],'delimiter','\t');

z=[xq',vq',vq2']

writematrix(z,'Interpolationdata.txt')
