Assume I have a code as below, how do we rewrite, so we can great reduce running time?
for i = 1: 500
% something to do
end

avoiding loop will reduce time. It depends on what is that something to do ?

Function can be formed and relate this to your main work i.e., something u have to do, this will reduce your running time.

There is no magic command to increase the speed like:
superspeedFor i = 1: 500
% something to do
end
As said before: You have to accelerate "something to do". If you can vectorize this part, the loop can be omitted, which is much faster in many situations.
