The matrix A 1 0 0 0 2 0 1 0 2 has lambda 2 as an eigenval

The matrix A = [-1 0 0 0 -2 0 1 0 -2] has lambda = -2 as an eigenvalue with multiplicity 2 and lambda = -1 as an eigenvalue with multiplicity 1. Find the associated eigenvectors. The eigenvalue -2 has associated eigenvector The eigenvalue -1 has associated eigenvector

Solution

I think that the given matrix is incorrect.

The eigenvector corresponding to eigenvalues -1 and -2 are 0.

Please recheck the question and post again.
