My code is here but I have faced problem with the output.
Input
x=load('BOD test.txt');
T = x;
net = narnet(1:2,10);
[Xs,Xi,Ai,Ts] = preparets(net,{},{},T);
net = train(net,Xs,Ts,Xi,Ai);
view(net)
Y = net(Xs,Xi,Ai);
plotresponse(T,Y)
Output
Index exceeds matrix dimensions.
Error in preparets (line 293)
xi = xx(:,FBS+((1-net.numInputDelays):0));
Error in riverdata (line 5)
[Xs,Xi,Ai,Ts] = preparets(net,{},{},T);
here is the txt file of BOD (1*18 matrix).

ALWAYS use the function WHOS to keep track of size and class for all variables. Then you would see that T and Y are not the same size. I consider it a typo that the syntax Y is used instead of Ys. Use the following
Ys = net(Xs,Xi,Ai);
plotresponse(Ts,Ys)
P.S. N = 18 is not long enough for a worthwile example
Hope this helps.
Thank you for formally accepting my answer
