Abstract: Abstract: Two tetradiagonal Toeplitz matrices perturbed by a (Formula presented.) 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). © 2023, Pleiades Publishing, Ltd.
