I have come across this command in matlab. rng(seed). I used the help to understand what its means, and I still don't get it. Can anyone help me understand what it does?
rng Control the random number generator used by RAND, RANDI, and RANDN.
rng(SD) seeds the random number generator using the non-negative
integer SD so that RAND, RANDI, and RANDN produce a predictable
sequence of numbers.
THanks.

Yes. You can think of the pseudorandom numbers from the generator as a long -- very long -- list of numbers that are uncorrelated with each other, and the seed determines where in that list you start.
