ON CENTROSYMMETRIC AND CENTROSKEW MATRICES
A. R. Collar · The Quarterly Journal of Mechanics and Applied Mathematics · 1962
Some properties of centrosymmetric matrices are described and discussed: in particular, methods are given for the determination of eigensolutions (latent roots and vectors) of centrosymmetric matrices from those of combinations of submatrices. Similar discussions are given for a class of matrix which may be described as centro-skew. Canonical forms for both centrosymmetric and centroskew matrices are given, and some applications are mentioned.
