Example: The eigenvalues of the 2×2 matrix − 2 1 2 1 come from solving the equation 2 1 2 1 = − − − . Thus, ) )( ( 2 1 2 1 = − − − and two eigenvalues are λ = +1/2 and λ = 1/2. Example: The eigenvalues of the 3×3 matrix − i i come from solving the equation = − − − − i i . Thus, λ ( λ 21)=0 and the three eigenvalues are λ = +1, λ = 0, and λ = 1....
