data = xlsread("project4.xlsx") %given xlsresad command to read the given file

V= data(:,1); %voltage value acording to the given sheet

I= data(:,2); % I values in the given sheet

xq = -17.3:0.1:0.9; %range

plot(V,I,'r+') %plotting of xq,y1

hold on

y1 = interp1(V,I,xq); %using interpolation command

plot(xq,y1,"b*") %plotting of xq,y1,

filename = fopen("project41.txt",'w') %saving file in text file

fprintf(filename,'%f\n ', y1);

fclose(filename);

result :

In ths project, it comprises of certain commands like interp1, where it helps to plot the unknown values between the selected range /values.

initial values of V,I represented with redcolur+ signs whereas, interpolation is with blue coloured * sign.
