Follow-up Comment #2, bug #53300 (project octave):
Mike said: And if a throwaway call to rand is made at the beginning, the state
is correct
This works for me and appears to be the only reliable
way to recover a previous sequence from randn.
At least, this should be clearly documented, including the need
to save the 'init_state' vector.
It is essential that users can reproduce results that were
previously computed. This is fundamental.
After this documentation, it would be good to put together
a better solution. It is reasonable to expect the generator
to use a default starting seed in any case.
