If the columns of A are linearly dependent - correct answer Then the matrix is not invertible and an eigenvalue is 0 Note that A−1 exists. In order for λ−1 to be an eigenvalue of A−1, there must exist a nonzero x such that Upper A Superscript negative 1 Baseline Bold x equals lambda Superscript negative 1 Baseline Bold x . A−1x=λ−1x. Suppose a nonzero x satisfies Ax=λx. What is the first operation that should be performed on Ax=λx so tha...

Example 1.10. There are six different 3 × 3 permutation matrices, namely ⎛ ⎝ 1 0 0 0 1 0 0 0 1 ⎞ ⎠, ⎛ ⎝ 0 1 0 0 0 1 1 0 0 ⎞ ⎠, ⎛ ⎝ 0 0 1 1 0 0 0 1 0 ⎞ ⎠, ⎛ ⎝ 0 1 0 1 0 0 0 0 1 ⎞ ⎠, ⎛ ⎝ 0 0 1 0 1 0 1 0 0 ⎞ ⎠, ⎛ ⎝ 1 0 0 0 0 1 0 1 0 ⎞ ⎠. (1.30) These have the following effects: if A is a matrix with row vectors r 1, r 2, r 3, then multiplication on the left by each of the six permutation matrices produc...
