Re:请问81.25%是怎么算出来的?我怎么算得是43.75%?In Reply To:Re:请问81.25%是怎么算出来的?我怎么算得是43.75%? Posted by:xiaomi at 2003-08-13 10:09:52 我还以为是 (4)=0.5(1)+0.5(2); (5)=0.5(2)+0.5(3); (6)=0.5(4)+0.5(5)=0.25(1)+0.5(2)+0.25(3); (7)=0.5(5)+0.5(6)=0.125(1)+0.5(2)+0.375(3); 所以(5)^(7)=0*0.125+0.5*0.5+0.5*0.375(做内积) 这么做呢 Followed by: Post your reply here: |
