1^F推larry310145:||Y-AX|| 為最小相當於滿足normal equation01/22 00:19

3^F推larry310145:你說的利用矩陣與反矩陣關係就是正規方程式AtAX=Atb01/22 07:16

4^F→larry310145:可以看看正規方程的推導就應該會懂了01/22 07:17

5^F→larry310145:如果A為行獨立那AtA就為可逆 X=[(AtA)^-1]Atb01/22 07:18

15^F推larry310145:為啥你前面沒有0/0 卻用L'hospotal?? 你的z=0的pole01/06 23:05

16^F→larry310145:已經先消掉了嗎??01/06 23:05

17^F→larry310145:照理說複變函數還是可以用L'hospotal 不是每個題目01/06 23:06

18^F→larry310145:都適合用Lorent expansion去找留數01/06 23:07

8^F推larry310145:這個可以切成四個矩陣分別求12/29 21:47

9^F推larry310145:我是把左上3x3叫A 右下2x2切開叫B12/29 23:02

10^F→larry310145:如果det(A) 或 det(B) 其中一個等於0 行列式就為零12/29 23:03

11^F→larry310145:然後分開求eigenvalue12/29 23:05
