Project - Data Handling and Interpolation

answer

data = readtable('VI.xlsx'); % Read the Excel file into a table

V = data.Voltage; % Extract the voltage

I = data.Current; % Extract the current data

xq = -17.3:0.1:0.9;% Define the range over which to interpolate

Vq = interp1(V, I, xq); % Interpolate the voltage

Iq = interp1(I, V, xq); % Interpolate current data

figure;% Create a figure

plot(Vq, Iq, 'bo'); % Plot the interpolated data

xlabel('Voltage (V)');

ylabel('Current (A)');

zoom on; % Enable interactive zoom

pan on; % Enable interactive pan

T = table(Vq, Iq);% Create a table with the interpolated data

writetable(T, 'interpolated_data.txt');% Write the table to a text file
