Abstract: This paper employs combinatorial computation techniques to derive the spectra, left and right eigenvectors of two classes of tridiagonal matrices, and establishes their orthogonality. Furthermore, closed-form expressions for the determinants of matrices formed by the corresponding eigenvectors are provided through elementary row and column transformations.
