A bidiagonalization-based numerical algorithm for computing the inverses of (p,q)-tridiagonal matrices

As a generalization of k -tridiagonal matrices, many variations of ( p , q )-tridiagonal matrices have attracted much attention over the years. In this paper, we present an efficient algorithm for numerically computing the inverses of n -square ( p , q )-tridiagonal matrices under a certain conditio...
