A Question on a Simple Loop

Hello. My problem: We have 5 machines. We wanna play each of these machines 1000 times (we call each 1000 plays a TASK). In each time, the machine gives us a reward (randomly). We wanna check that the mean reward of which one of these TASKs is more than others (maximum). I wrote this code but it doesn't work well. Why?
for j=1:5
h=0;
for i=1:1000
rew=randn(1);
sum=rew+h;
end
mean(j)=sum./1000; [value,index]=max(mean(j))
end end
Thanks in advance

Do not use "sum" as the name of a variable or you will almost always encounter problems with sum() being the name of a useful MATLAB function.

You never update "h" so at each point "sum" will be assigned only the latest random value.
