請問這題每個選項的理由。
9.Choose the incorrect arguments.
(a) Let A be the Hermitian matrix.Then, matrix A is diagonalizable ; that is , A = X^-1DX
(b) For a square matrix A, the eigenvectors correspond to different eigenvalues are linearly independent.
(c) Two similar matrices have the same characteristic polynomial.
(d) Let A be an m*n real matrix. Then A^TA is diagonalizable .
(e) Let matrix A be diagonalizable. Then , matrix A is not singular.
另外想問一下,a和d選項的觀念是那個章節裡有談到,我想加強一下。謝謝助教。
還有第十題:
