Abstract:
Two tetradiagonal Toeplitz matrices perturbed by a
$2\times2$ matrix at the upper right corner are examined.
Their
LU-decompositions are explicitly given.
As a consequence, their
determinant evaluations confirm the conjectured determinant
values of two numerical matrices made recently by Andelić and Fonseca (2020).
Keywords:
Toeplitz matrix, tetradiagonal matrix,
LU-decomposition, determinant.
