I am trying to do an asynchronous, random order update for a Hopfield neural network. Here is my code:

S=U;
Async=randperm(50);
m19(1)=(S*U')/N;
for t= Async(2:end)
   h(t)=(W2(t,:)*S')/N;
   S(t)=sign(h(t));
   m19(t)=(S*U')/N;
end
figure
plot(m19)
title('Overlap between S and U with W2')

However, I need to make it so that the number 1 is not included in the code for Async (because I need to use the number 1 to calculate m(19) - the overlap - then need all numbers after 1 to be random).
