※ 引述《wawawochi (granada)》之銘言： : 親愛的統計系同學，小弟資質魯鈍，麻煩你們幫我想一下怎樣證明!!感激不盡!! : 1. Let A be an m×n matrix. Show that 0 < = rank(A) < = min{m, n} : (小於等於) (小於等於) 用pivot 這要看你rank的定義定義不一樣寫法不一樣 : 2. Show that the rank of a diagonal matrix equals the number of nonzero : diagonal elements it possesses. Is the same true for a triangular matrix? : 感謝啦!!!! 同上否 0 0 1 0 -- I live in Taipei. I have a sister. I have no dog. I have no cat. I have no bird. However, i want a pet. So i treat my sister as my pet. 英文自介... 我真的交出去了 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.114.207.81
