Project - Data Handling and Interpolation

Code

%data import

voltageVScurrent = readtable('VI.xlsx','PreserveVariableNames',true);

%interpolation

xp1 = -17.3:0.1:0.9;

xp2 = interp1(voltageVScurrent.("V (Volt)"),voltageVScurrent.("I (mAmp)"), xp1);

plot(voltageVScurrent.("V (Volt)"),voltageVScurrent.("I (mAmp)"),'o',xp1,xp2,':');

%exporting data as text file

fid = fopen('Output.txt','wt');

fprintf(fid,'%.3f\t',xp2);

fclose(fid);
