linear interpolation using 2 arrays

I have two separate arrays containing two variables, t & T. I need to interpolate for a new set of T values using the relationship between t and T.
for k=1:length(t)
[t, index] = unique(t);
tr_T = interp1(t,T(index),'linear'); %linear interpolation to find new T given t
end
However, the shape of the original T curve is not retained after I interpolate and derive the tr_T values. Any ideas?

The "yellow" curve is red, isn't it?
The intention of the shown code is not clear. Calculating "[t, index] = unique(t)" repeatedly in each iteration does not change the result and tr_T is overwritten again and again.
What are the two arrays t and T? Why do you use the indices of the unique value of t to get values from T? This looks strange.
