WebDec 1, 2024 · What are Eigenvectors and Eigenvalues. An eigenvector of a matrix A is a vector v that may change its length but not its direction when a matrix transformation is applied. In other words, applying a matrix transformation to v is equivalent to applying a simple scalar multiplication. A scalar can only extend or shorten a vector, but it cannot ... WebSep 17, 2024 · Eigenvalues and eigenvectors are only for square matrices. Note 5.1.2 Eigenvectors are by definition nonzero. Eigenvalues may be equal to zero. We do not consider the zero vector to be an eigenvector: since A0 = 0 = λ0 for every scalar λ, the associated eigenvalue would be undefined.
