|A circulant matrix whose elements are square submatrices is called a compound-circulant matrix. The eigenvectors and eigenvalues had been found for symmetric compound-circulant matrices, and that method is extended to general|
compound-circulant matrices. That analysis is applied to Stephen J. Watson's
alternating circulant matrices, which reduce to compound-circulant matrices with
square submatrices of order 2.
