Project - Data Handling and Interpolation
%Answer
A = xlsread('VI.xlsx');
V = A(:,1);
I = A(:,2);
x = [-17.3:0.1:0.9];
y = interp1(V,I,x,'spline')
plot(V,I,'r',x,y)
intervoltage =[I, V]
intercurrent = interp1(V,I,intervoltage)
Z = [intervoltage intercurrent]
field = fopen('intervoltage intercurrent.txt','w');
fprintf("%f",Z);
fclose(field)
