WebApr 27, 2024 · Eigenvalues and Eigenvectors. Definition 1: Given a square matrix A, an eigenvalue is a scalar λ such that det (A – λI) = 0, where A is a k × k matrix and I is the k × k identity matrix. The eigenvalue with the largest absolute value is called the dominant eigenvalue. Observation: det (A – λI) = 0 expands into a kth degree polynomial ... WebFor λ = − 2, let x = ( x 1, x 2, x 3) be an eigenvector corresponding to − 2. Then, A x = − 2 x, and multplying the matrix A by x you obtain the following system of equations: − 5 x 1 − 6 x 2 + 3 x 3 = − 2 x 1 3 x 1 + 4 x 2 − 3 x 3 = − 2 x 2 0 x 1 + 0 x 2 − 2 x 3 = − 2 x 3 From the last equation it is clear that x 3 = 0.
