WebMar 20, 2016 · Solving this you get both eigenvalues of $\lambda_1 = \lambda_2 = 1$. You can see from this how a diagonal matrix greatly simplifies your calculations. In a diagonal matrix the diagonal terms are your eigenvalues. Try recalculcating your eigenvectors with these eigenvalues. You will get $[0,\ 1]^T$ and $[1,\ 0]^T$. Hope this helps. WebSep 17, 2024 · The expression det (A − λI) is a degree n polynomial, known as the characteristic polynomial. The eigenvalues are the roots of the characteristic polynomial det (A − λI) = 0. The set of eigenvectors associated to the eigenvalue λ forms the eigenspace Eλ = \nul(A − λI). 1 ≤ dimEλj ≤ mj. WebFeb 1, 2016 · It turns out that the smallest value of t for which the matrix power P^t is equal to the identity matrix is t = 8 for P = Pout and t = 52 for P = Pin. Eigenvalues. All of this is explained by eigenvalues. The matrix Pout has order 52, but only 8 distinct eigenvalues, namely the 8-th roots of unity. remanufactured dodge 4.7l engine
