Eigenvalues and eigenvectors - Wikipedia

WebThe eigenvalues and eigenvectors of unitary matrices have some special properties. If U U is unitary, then U U † = I. U U † = I. Thus, if U v = λ v (4.4.1) (4.4.1) U v = λ v 🔗 then also v U † = v λ∗. (4.4.2) (4.4.2) v U † = v λ ∗. 🔗 Combining (4.4.1) and (4.4.2) leads to WebJul 1, 2024 · The eigenvectors of a matrix A are those vectors X for which multiplication by A results in a vector in the same direction or opposite direction to X. Since the zero vector 0 has no direction this would make no sense for the zero vector. As noted above, 0 is never allowed to be an eigenvector.
