B-Matrices and Doubly B-Matrices in the Interval Setting

In this paper we focus on generalizing B-matrices and doubly B-matrices into interval setting, including some results regarding these classes. By interval B-matrix, or doubly B-matrix we understand such an inte...

Explicit Inverse of an Interval Matrix with Unit Midpoint

Explicit formulae for the inverse of an interval matrix of the form [I -D, I +D] (where I is the unit matrix) are proved via finding explicit solutions of certain nonlinear matrix equations....

Inverse Interval Matrix: A Survey

Results on the inverse interval matrix, both theoretical and computational, are surveyed. Described are, among others, formulae for the inverse interval matrix, NP-hardness of its computation, various classes of

On relation between P-matrices and regularity of interval matrices

We explore new results between P-matrix property and regularity of interval matrices. In particular, we show that an interval matrix is regular in and only if some also investigate the converse direction. We reduce...

Interval matrices: Regularity generates singularity

It is proved that regularity of an interval matrix implies singularity of four related interval matrices. The result is used to prove that for each nonsingular point matrix A, either A or A^-1 can be brought to a s...

BpiR-Matrices, B-Matrices, and Doubly B-Matrices in the Interval Setting

BpiR-matrices into the interval setting, but we prove that, in a sense, they are one. We derive mainly recognition methods for this interval matrix classIn this paper, we focus on generalizing BpiR-matrices into the in...

A Characterization of Strong Regularity of Interval Matrices

As the main result of this paper it is proved that an interval matrix is strongly regular if and only if certain the matrix inequality has a solution. Several consequences of this result are drawn....

An Eigenvalue Symmetric Matrix Contractor

We propose an eigenvalue contractor for symmetric matrices. Given a symmetric interval matrix A and an interval approximation of its eigenvalue sets the contractor reduces the entries of A such that no matrix with ...
