چکیده
|
This paper examines suitable borderings and modification techniques for finding some special properties of a class of real heptadiagonal symmetric toeplitz matrices and anti-heptadiagonal persymmetric hankel matrices with perturbed corners as the zeros of explicit rational functions. an orthogonal diagonalization, inverse and determinant, and a formula to compute its integer powers for these matrices are shown. then, these results are expanded for the corresponding toeplitz-plus-hankel matrices with perturbed corners.
