[線代] 矩陣的計算

[mqazz1 (無法顯示)]

1. Let A in R^(3*3)

    [1 1 1]           [2 0  0]      T [x]   [x]
P = [2 3 3], if AP = P[0 1  0] and A  [y] = [y]
    [1 3 4]           [0 0 -1]        [1]   [1]


then (x,y) = ?


       [ 1  2  3  4 ]           3    2
2. H = [ 5  6  7  8 ]. suppose H = aH + bH + cI,  a,b,c in R
       [ 9 10 11 12 ]
       [13 14 15 16 ]

   (a,b,c) = ?

   這題應該是C-H 可是很難算


請問有人知道這兩題怎麼解嗎?

謝謝
