WebThe eigenvalues of a Hermitian matrix are real, since (λ− λ)v= (A*− A)v= (A− A)v= 0for a non-zero eigenvector v. If Ais real, there is an orthonormal basis for Rnconsisting of eigenvectors of Aif and only if Ais symmetric. It is possible for a real or complex matrix to have all real eigenvalues without being Hermitian. WebNov 15, 2014 · For 3x3 matrices, a very slick implementation is possible by building the orthogonal transform out of rotations and representing them as a Quaternion.
