I see that now:
" By default, the generator is initialized from `/dev/urandom' if it
     is available, otherwise from cpu time, wall clock time and the
     current fraction of a second."
Descriptions is very clear :-) but I was wondering why is the default behavior different than the one of C and matlab rand() functions?

No, rand() isn't always seeded to the same state. Please read "help
rand" for a description of this. If you find this description
confusing, please state how, so we can improve it.
