Abstract

We present a proof of determinant of special nonsymmetric Toeplitz matrices conjectured by Anđelic and Fonseca in \cite{andjelic2020some}. A proof is also demonstrated for a more general theorem. The two conjectures are therefore just two possible results, under two specific settings. Numerical examples validating the theorem are provided.
