how to close rng 'default' after using it once in a same program

Suppose, there is a scenario where I am using random number generator(rand(n,1)) which I need to fix for the values of a variable for a loop. So, I am using the command rng 'default'. Again in the same program I need to vary the random numbers in some other loops. But for For this I need to stop rng 'default ' command. Can anybody tell me how to do this?
Thanks in advance.

I don't recommend setting rng('default') within a loop, if that's what you're doing. That defeats the purpose of using a random process since every iteration would have the same sequence of random numbers. If you need to keep track of the random number generator seed for each iteration of a loop, you can store it like this.
n = 5
rngState = [];
for i = 1:n
rngState = [rngState; rng()];
% Your code here
end
seeds = [rngState.Seed]
