Eigenvalues and eigenvectors

The eigenvectors with eigenvalue λ,if any, are the nonzero solutions of the equation Av=λv. We can rewrite this equation as follows: Av=λv⇐⇒Av−λv=0⇐⇒Av−λInv=0⇐⇒(A−λIn)v=0.

Math 2331 – Linear Algebra

The eigenvalues of A are the roots of the characteristic polynomial p(λ) = det (A– λI). For each eigenvalue λ, we find eigenvectors v = [v1 v2 ⋮ vn] by solving the linear system (A– λI)v = 0. The set of all vectors v satisfying Av = λv is called

5.1: Eigenvalues and Eigenvectors

A100 was found by using the eigenvalues of A, not by multiplying 100 matrices. Those eigenvalues (here they are 1 and 1=2) are a new way to see into the heart of a matrix. To

Linear Algebra — Part 6: eigenvalues and eigenvectors

These are also called eigenvectors of A, because A is just really the matrix representation of the transformation. So in this case, this would be an eigenvector of A, and this would be the eigenvalue
