The authors show that an arbitrary square matrix can be expressed as sums of products of Hessenberg algebra matrices and high level (block) matrices whose submatrices are Hessenberg algebra matrices. In most cases these block factors are block-diagonal. This result is applied in sequential and parallel solution of Toeplitz systems.
