using smoothed data in FOR loop

hi

I wrote a code in a for loop, in the code a variable is updating and another variable is effected by, the first variable is so noisy at the end of the loop and I want the smoothed one. I have used the smooth order but it works at the end of loop and in the loop it does not work for example I want the first data in the loop be the first data of the smoothed one etc.

this is the code:

for i = 1:15000
.
.
.
T2(i) = .........
x(i) = 5*T2(i);
end

the T2 is

and the smoothed one is:

i used the smooth order in the loop as:

for i = 1:15000
    .
    .
    .
    T2(i) = . . . .
    T2(i) = smooth(T2(i),0.1,'rloess');
    x(i) = 5*T2(i);
end

but it does not work!
