P is symmetric, so its eigenvectors .1;1/ and .1; 1/ are perpendicular. The only eigenvalues of a projection matrix are 0 and 1. The eigenvectors for D 0 (which means Px D 0x/ fill up the nullspace. The eigenvectors for D 1 (which means Px D x/ fill up the column space. The nullspace is projected to zero. The column space projects onto itself.

1. Markov matrix: Each column of P adds to 1, so λ = 1 is an eigenvalue. 2. P is singular, so λ = 0 is an eigenvalue. 3. P is symmetric, so its eigenvectors (1,1) and (1,−1) are perpendicular. The only eigenvalues of a projection matrix are 0and 1. The eigenvectors for λ = 0(which means Px = 0x)fill up the nullspace.
