Properties of symmetric matrix eigenvalues
WebAn example of the eigenvalue and singular value decompositions of a small, square matrix is provided by one of the test matrices from the Matlab gallery. A = gallery(3) The matrix is A = −149 −50 −154 537 180 546 −27 −9 −25 . This matrix was constructed in such a way that the characteristic polynomial factors nicely: det(A−λI ... WebSymmetric matrices play the same role as the real numbers do among the complex numbers. Their eigenvalues often have physical or geometrical interpretations. One can …

WebDepolarization has been found to be a useful contrast mechanism in biological and medical imaging. The Mueller matrix can be used to describe polarization effects of a depolarizing … WebSince the eigenvalues of a real skew-symmetric matrix are imaginary, it is not possible to diagonalize one by a real matrix. However, it is possible to bring every skew-symmetric matrix to a block diagonal form by a special orthogonal transformation.
