A Diagonalization Algorithm for the Distance Matrix of Cographs

open access: yesIEEE Access, 2018
Cographs is a well-known class of graphs in graph theory, which can be generated from a single vertex by applying a series of complement (or equivalently join operations) and disjoint union operations.

Bayesian Estimation of A Distance Functional Weight Matrix Model [PDF]

open access: yes
This paper considers the distance functional weight matrix in spatial autoregressive and spatial error models from a Bayesian point of view. We considered the Markov chain Monte Carlo methods to estimate the parameters of the models.

Sufficient conditions for symmetric matrices to have exactly one positive eigenvalue

open access: yesSpecial Matrices, 2020
Let A = [aij] be a real symmetric matrix. If f : (0, ∞) → [0, ∞) is a Bernstein function, a sufficient condition for the matrix [f (aij)] to have only one positive eigenvalue is presented.

Bounds for the componentwise distance to the nearest singular matrix

open access: yes, 1997
The normwise distance of a matrix A to the nearest singular matrix is well known to be equal to ∥A∥/cond(A) for norms subordinate to a vector norm. However, there is no hope for finding a similar formula or even a simple algorithm for computing the ...
