AbstractA class Σ of matrices is studied which contains, as special subclasses, p-circulant matrices (p ⩾ 1), Toeplitz symmetric matrices and the inverses of some special tridiagonal matrices. We give a necessary and sufficient condition in order that matrices of Σ commute with each other and are closed with respect to matrix product
