If A is a real n × n matrix which is orthogonal and symmetric, then A 2 = A A T = I. Therefore the eigenvalues of A are all equal to ± 1. If also A is positive definite then they must all be equal to 1. Finally, A is diagonalizable since it is symmetric, and since all the eigenvalues of A are equal to 1 it follows that A is the identity ...

The inverse square root of a matrix plays a role in the computation of an optimal symmetric orthogonalization of a set of vectors. We suggest two iterative techniques to compute an inverse square root of a given matrix. The two schemes are analyzed and their numerical stability properties are investigated. rookery cdWebces to add to those on our list: triangular, diagonal, permutation, symmetric, reduced row echelon, and projection matrices.
