This paper introduces a new type of tridiagonal matrix, where the matrix entries are defined by an integer sequence, setting it apart from the classical Sylvester-Kac matrix. The aim of this paper is to investigate several fundamental properties of this generalized matrix, including its algebraic structure, determinant, inverse, LU decomposition, characteristic polynomial, and various norms.eninfo:eu-repo/semantics/closedAccessCharacteristic PolynomialDeterminantNormSylvester–Kac MatrixTridiagonal MatrixA new approach to tridiagonal matrices related to the Sylvester-Kac matrixArticle31221122710.7546/nntdm.2025.31.2.211-227WOS:001515308200001Q3
