WebThm: A matrix A 2Rn is symmetric if and only if there exists a diagonal matrix D 2Rn and an orthogonal matrix Q so that A = Q D QT = Q 0 B B B @ 1 C C C A QT. Proof: I By …
Webvectors and P is orthogonal. Proposition An orthonormal matrix P has the property that P−1 = PT. Theorem If A is a real symmetric matrix then there exists an orthonormal matrix P such that (i) P−1AP = D, where D a diagonal matrix. (ii) The diagonal entries of D are the eigenvalues of A. (iii) If λ i 6= λ j then the eigenvectors are ... WebAn orthogonal matrix, or a matrix with orthonormal columns, is a real matrix whose columns all have unit length and are perpendicular to each other. If Q is orthogonal, ... This ensures that the diagonal elements of R occur in decreasing order and that any linear dependence among the columns is almost certainly be revealed by examining these ...
