WebCirculant matrices arise in the study of periodic or multiply symmetric dynamical systems. In particular they have application in the theory of crystal structure [1]. The history of circulant matrices is a long one. In this paper a (block-diagonal) canonical form … WebEigenvalues of complex symmetric circulant matrices. A square matrix A is called Hermitian, if and only if A∗= A. If the matrix is real, this reduces to AT= A. Each Hermitian matrix has a full set of orthogonal eigenvectors, each with real eigenvalue. The complex circulant matrix B in (1) is symmetric if and only ifbj=bn−j forj= 1,2,··· ,(n −1)÷2.
