K=100;
a=zeros(K,1);
for u = 0:K-1
for b = 0:K-1
a(u+1) = a(u+1) + s(b+1)*exp((-2j*pi*u*b/K));
end
end

Well you could try meshgrid() but I think it might make it a little more confusing to understand what it's doing. With only 100x100 array to fill, a double for loop will be very fast so even if you did vectorize it, don't expect to notice any speed difference.
