33^F推rick6304: 之前做專題有看過類似的書但書名忘了結論是09/18 15:32

34^F→rick6304: 投千萬分之一的錢去玩C09/18 15:32

[線代] 不同向量空間如何做內積?

作者: rick6304 - 發表於 2015/05/26 21:51(10年前)

5^F→rick6304: 意思是說只要滿足內積空間的定義 R3向量不一定要是05/26 23:18

6^F→rick6304: a*a1+b*b1+c*c1 是嗎?05/26 23:18

11^F→rick6304: 那所以對任意向量空間我可以自己定規則是嗎?05/26 23:21

13^F→rick6304: 不好意思可否請教內積的抽象定義是指?05/26 23:23

16^F→rick6304: 抱歉又有問題..u內積v定義是絕對值u*v*uv夾角05/26 23:39

17^F→rick6304: 但...怎麼知道多項式或矩陣的絕對值...05/26 23:39

20^F→rick6304: 那是剛翻課本的所以那個只能說明R^N的內積05/26 23:57

21^F→rick6304: 而正確的內積是滿足微基說的共軛線性正定是嗎?05/26 23:58

22^F→rick6304: 或是說可以用在任意向量空間的內積定義05/26 23:59

23^F→rick6304: 感謝感謝重看過一次我懂了謝謝05/27 00:29
