Block diagonalization of (p, q)-tridiagonal matrices
In this article, we study the block diagonalization of (p,q)\left(p,q)-tridiagonal matrices and derive closed-form expressions for the number and structure of diagonal blocks as functions of the parameters pp, qq, and nn. This reduction enables efficient computation of eigenvalues and eigenvectors b...
