Numerical values into plot issue

I created a code that takes an initial guess for a distribution and then modifies it. After completing the code it then is supposed to plot the modified distribution, however it is plotting both the guess values and final values. My guess looks something like:
Tfuel = zeros(nr+1);
Tfuel(:) = 800;
The guess is then modified very much like the following statement:
Ttemp=0.5*dr*dr*(qvol/k+Tfuel(i+1)/(dr*dr)+Tfuel(i-1)/(dr*dr)+...
Tfuel(i+1)/(2*dr*dr*i)-Tfuel(i-1)/(2*dr*dr*i));
Ttemp=(1-w)*Tfuel(i)+w*Ttemp;
Tfuel(i)=Ttemp;
I used the basic plot command as:
plot(r,Tfuel)
Any idea why this is occurring? I have never had this issue before.
Thanks

I suspect maybe you want
Tfuel = zeros(nr+1,1);
instead of
Tfuel = zeros(nr+1);
With the above you are creating a nr+1-by-nr+1 matrix and then with
Tfuel(:) = 800;
You are filling the whole matrix with 800. Then in your loop
Tfuel(1) % or whatever you index i is
You are only filling the first column.
