Tångavägen 5, 447 34 Vårgårda info@futureliving.se 0770 - 17 18 91 If is Hermitian (symmetric if real) (e.g., the covariance matrix of a random vector)), then all of its eigenvalues are real, and all of its eigenvectors are orthogonal. Given the eigenvector of an orthogonal matrix, x, it follows that the product of the transpose of x and x is zero. An orthogonal matrix Q is necessarily invertible (with inverse Q −1 = Q T), unitary (Q −1 = Q ∗),where Q ∗ is the Hermitian adjoint (conjugate transpose) of Q, and therefore normal (Q ∗ Q = QQ ∗) over the real numbers. Thus, if matrix A is orthogonal, then is A T is also an orthogonal matrix. The calculator will find the eigenvalues and eigenvectors (eigenspace) of the given square matrix, with steps shown. The determinant of any orthogonal matrix is either +1 or −1. In the same way, the inverse of the orthogonal matrix, which is A-1 is also an orthogonal matrix. We prove that eigenvectors of a symmetric matrix corresponding to distinct eigenvalues are orthogonal. MATH 340: EIGENVECTORS, SYMMETRIC MATRICES, AND ORTHOGONALIZATION Let A be an n n real matrix. A real symmetric matrix H can be brought to diagonal form by the transformation UHU T = Λ, where U is an orthogonal matrix; the diagonal matrix Λ has the eigenvalues of H as its diagonal elements and the columns of U T are the orthonormal eigenvectors of H, in the same order as the corresponding eigenvalues in Λ.
