Let A be the matrix of coefficients, then ( A ⋅ x) k = λ x k. Add the third and the second row. This gives x 2 + x 3 = λ ( x 2 + x 3), thus λ = 1 or x 2 + x 3 = 0. Since the trace of A equals 1, the sum of other two eigenvalues is 0.

WebThe Gershgorin circle theorem comes close to estimating the eigenvalues by 'inspection' - by summing the absolute values of the row elements (except the ones on the diagonal). So in this case the three eigenvalues are all in the interval [3-4,3+4]. Share Cite Follow answered Jun 2, 2012 at 13:33 user11260 1 Thanks for posting this. WebNow as a second eigenvector for F with eigenvalue 2 choose a vector with a nonzero entry in the third column, a 1 in its second column, and zeros elsewhere, say v = (0, 1, -1, 0) T.
