2 2 Let(x)=Ax be the linear transformation from R to R that reflects [4] any vector onto the line L spanned by the vector[3] (a) Find the eigenvalues and their corresponding eigenvectors for the transformation matrix A 我看小黃解答： [-3/5] 取u= [4/5 ] 為直線L的單位反向量然後求 t Householder matrix為 A=I-2uu A= [7/25 24/25 ] [ ] [24/25 -7/25] 我代A([4])進去出來還是 [4] ..... ，不是要可以reflect L上的任一點嗎？ [3] [3] 那小黃求Householder矩陣要幹嘛，帶進去竟然不會反射 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 220.138.110.230
