• Data Handling and Interpolation

% Read the excel file

data = xlsread('VI.xlsx');

voltage = data(:,1);

current = data(:,2);

% Find missing data and interpolate

v = -17.3:0.1:0.9;

i = interp1(voltage,current,v);

% Generate interactive plot

figure;

plot(voltage,current,'o',v,i);

title('Voltage vs Current');

xlabel('Voltage');

ylabel('Current');

legend('Original data','Interpolated data','Location','NorthWest');

grid on;

% Save interpolated data to text file

output = [v' i'];

dlmwrite('interpolated_data.txt', output, 'delimiter', '\t');

Here's a brief explanation of what the code does:

The code reads the excel file "VI.xlsx" using the xlsread function and stores the voltage and current data in separate arrays.

The code generates a new set of voltage values v using the range -17.3:0.1:0.9.

The code interpolates the current data at the new voltage values using the interp1 function.

The code generates an interactive plot of the original and interpolated data using the plot function.

The code saves the interpolated data to a text file "interpolated_data.txt" using the dlmwrite function.
