For a given (n, n) matrix A = (a ik ) the eigenvalue problem consists of finding nonzero vectors x so that A x is parallel to the vector x. Such a vector x is called an eigenvector of A. It satisfies the eigenvalue-eigenvector equation for a scalar 位, called the eigenvalue:...
Definition of eigenvalues and eigenvectors of a matrix Let A be any square matrix. A non-zero vector v is an eigenvector of A if Av = λv for some number λ, called the corresponding eigenvalue.NOTE: The German word "eigen" roughly translates as "own" or "belonging to". Eigenvalues ...
Figure A6.1. Eigenvector v=(1,1) of matrix A. Note that the product Av does not change the direction of v; it only scales it by the eigenvalue λ (7 in this example). This is essentially the property associated with eigenvectors and eigenvalues of a matrix A, here v and λ, respe...
