seed twister t distribution
Hi there, I am a little confused about restating the seed. When I start matlab: x=exprnd(3,1,4) ans=0.6147 0.2968 6.1910 0.2718 rand('twister', 5489); x=exprnd(3,1,4) ans=0.6147 0.2968 6.1910 0.2718 This way I restate the seed and get the same 4 numbers. But when I do the same th... 26 Sep 2009 10:15
