Abstract: A normal, paramount, tridiagonal matrix is shown to be the inverse of a one-pair uniformly tapered matrix, and as such to be realizable as the impedance matrix of a resistive n-port network.

Matrix classes for matrices that are block-tridiagonal and sparse, and simply "block sparse". These talk together, and furthermore containts an algorithm for inversion of the block-tridiagonal version ...

We put forward and prove a simple theorem stating that the eigenvalues of a tridiagonal matrix change their sign (as a set), once the signs of the diagonal elements of the matrix are changed. We also ...
