Subject: restoring state of rand()

Hello,

"help rand" tells me that

<quote>
You can query the state of the random number generator using the
form
          v = rand ("state")
This returns a column vector V of length 625. Later, you can
restore the random number generator to the state V using the form
          rand ("state", v)
</quote>

but my mileage varies:

octave:1> help rand
octave:2> v = rand("state");
octave:3> rand(3,1)
ans =

  0.82058
  0.29780
  0.98109

octave:4> rand("state",v);
octave:5> rand(3,1)
ans =

   4.4409e-17
   4.4409e-17
   4.4409e-17

Can anyone help me out? I'm using octave-forge compiled against octave 2.1.57

Michael
