TOEPLITZ BASES IN MATRIX FIELDS

Analysis, 1988
The authors establish several criteria in order that the family of unit vectors \((e^ k)_{k\geq 1}\) should be a Toeplitz T-basis in a matrix field \(E_ A\), where T is a lower triangular matrix and E is a BK-space. Firstly, they give a characterization theorem in general hypotheses.

Efficient inversion of Toeplitz-block Toeplitz matrix

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1983
An iterative algorithm for the inversion of a Toeplitz-block Toeplitz matrix consisting of \(m\times m\) blocks of size \(p\times p\) is described. The algorithm presented exploits the spectrum of the Toeplitz-block Toeplitz matrix and outperforms \textit{H. Akaike}'s algorithm [see SIAM J. Appl. Math. 24, 234-241 (1973; Zbl 0234.65039)] by a factor of

Block Toeplitz Matrix Inversion

SIAM Journal on Applied Mathematics, 1973
An iterative procedure for the inversion of a block Toeplitz matrix is given. Hitherto published procedures are obtained as special cases of the present procedure. The use of the procedure in time series analysis is briefly explained.
