What “eigenvalue” means
Wiktionary · Wikipediaeigenvalue/ˈaɪɡənˌvæljuː/
- nounA scalar, \lambda, such that there exists a non-zero vector x (a corresponding eigenvector) for which the image of x under a given linear operator \mathrm{A} is equal to the image of x under multiplication by \lambda; i.e. \mathrm{A} x = \lambda x.
In linear algebra, an eigenvector or characteristic vector is a (nonzero) vector that has its direction unchanged by a given linear transformation. More precisely, an eigenvector of a linear transformation is scaled by a constant factor when the linear transformation is applied to it: . The corresponding eigenvalue, characteristic value, or characteristic root is the multiplying factor .
