Similar matrices have the same characteristic equation (and, therefore, the same eigenvalues). . Nonzero vectors in the eigenspace of the matrix A for the eigenvalue λ are eigenvectors of A.Eigenvalues and Eigenvectors of a 3 by 3 matrix. Just as 2 by 2 matrices can represent transformations of the plane, 3 by 3 matrices can represent transformations of 3D space.
