MATLAB: Is it possible to get the actual random seed

getrandrandomrngseed

Is it possible to get the number x, for which rng(x) has no effect on random generation?

s = rng;

will retrieve and store the current state of the random number generator, according to this documentation page.

Then,

rng(s)

will restore it to that state.

s = rng;   % rng seeds the random number generator
seq1 = rand(1,5);
rng(s);
seq2=rnd(1,5);
