setrandstate

 function setrandstate(flag)

 <flag> (optional) is
   0 means seed to 0
   1 means seed to sum(100*clock)
   {N} means seed to N
   default: 1.

 induce randomness by setting the state of rand and randn.

 example:
 setrandstate;

0001 function setrandstate(flag)

0003 % function setrandstate(flag)

0005 % <flag> (optional) is
0006 %   0 means seed to 0
0007 %   1 means seed to sum(100*clock)
0008 %   {N} means seed to N
0009 %   default: 1.
