How to solve eigenvector problems

WebSep 17, 2024 · An eigenvector of A is a nonzero vector v in Rn such that Av = λv, for some scalar λ. An eigenvalue of A is a scalar λ such that the equation Av = λv has a nontrivial solution. If Av = λv for v ≠ 0, we say that λ is the eigenvalue for v, and that v is an … WebTo find the eigenvectors of A, substitute each eigenvalue (i.e., the value of λ) in equation (1) (A - λI) v = O and solve for v using the method of your choice. (This would result in a system of homogeneous linear equations. To know how to solve such systems, click here .)
