WebThe classical approach, which characterizes eigenvalues as roots of the characteristic polynomial, is actually reversed. If A is an n-by-n matrix, poly(A) produces the coefficients p(1) through p(n+1), with p(1) = 1, in. WebThe characteristic equation. In order to get the eigenvalues and eigenvectors, from A x = λ x, we can get the following form: ( A − λ I) x = 0. Where I is the identify matrix with the same dimensions as A. If matrix A − λ I has an inverse, then multiply both sides with ( A − λ I) − 1, we get a trivial solution x = 0. Web1 Take an eigen vector v corresponding to an eigenvalue λ . Use this fact and cacluate A 2 v and 6 A v independently, and equate them using the information A 2 = 6 A; that will give you a condition on λ enabling you to guess it.
