matlab rand('seed) 在 Re: [問題] random seed - 看板MATLAB - 批踢踢實業坊 的推薦與評價
※ 引述《Fibre (= =..)》之銘言:
: 請問如何控制 random seed (factor) ?
: 我看了help ---> rand('seed',N)
當你給了一個seed之後
生出來的亂數就是一組固定的值
例如
rand('seed',100)
rand('seed')
ans = 100 =>你的seed設為100
rand(1)
ans = 0.2909 =>你用100這個seed得到的亂數
rand('seed')
ans = 3351868 =>當你生了一組亂數之後 seed就會變成另外一個數(也是固定的)
rand('seed',100) %seed設回100
rand(1)
ans = 0.2909 =>結果還是一樣
這就表示當你用一樣的seed的時候無論何時都會得到同一組亂數
: 卻看不懂如何使用 有人可以幫個忙講解一下嗎?
: (由於需要去trace每次的隨機部分的運算結果 需要去固定random seed)
: 謝謝各位大大 Q.Q
