Identities involving negative- indexed Pell and Pell–Lucas numbers are derived using the determinants and traces of these matrices. Furthermore, we examine various powers of the constructed matrices and discuss related elementary matrix operations.eninfo:eu-repo/semantics/openAccessPell numbersPell-Lucas numbersMatrix theoryArticle46490291010.17776/csj.1674240
