[理工] 線代-求不變子空間
Let A be a 2x2 matrix , and call a line through the origin of R^2 invariant
under A if Ax lies on the line when x does, Find equations for all lines in
R^2 , if any, that are invariant under the matrix A = [ 4 -1 ]
[ 2 1 ]

黃老師例題的一題, 能找出 w= ax+by=0
這時候要考慮兩種情況 ,一是a=0 和 a!=0 ,這時候就比較看不懂了
能告訴我思考方向嗎?
