Interval-valued Fuzzy Matrices with Interval-valued Fuzzy Rows and Columns

Fuzzy Information and Engineering, 2015
Fuzzy matrix (FM) is a very important topic of fuzzy algebra. In FM, the elements belong to the unit interval [0,1]. When the elements of FM are the subintervals of the unit interval [0,1], then the FM is known as interval-valued fuzzy matrix (IVFM).

An Inverse Spectral Problem for the Matrix Sturm-Liouville Operator with a Bessel-Type Singularity

International Journal of Differential Equations, 2015
The inverse problem by the Weyl matrix is studied for the matrix Sturm-Liouville equation on a finite interval with a Bessel-type singularity in the end of the interval.

On the Interval Generalized Coupled Matrix Equations

The Electronic Journal of Linear Algebra, 2018
In this work, the interval generalized coupled matrix equations \begin{equation*} \sum_{j=1}^{p}{{\bf{A}}_{ij}X_{j}}+\sum_{k=1}^{q}{Y_{k}{\bf{B}}_{ik}}={\bf{C}}_{i}, \qquad i=1,\ldots,p+q, \end{equation*} are studied in which ${\bf{A}}_{ij}$, ${\bf{B}}_{ik}$ and ${\bf{C}}_{i}$ are known real interval matrices, while $X_{j}$ and $Y_{k}$ are the unknown ...

Interval State Estimation of Electricity-Gas Systems Considering Measurement Correlations

Energies
The popularization of electricity-gas systems leads to increasing demand for state management of systems. However, the existence of neglected measurement correlations brings uncertainties to the electricity-gas systems state estimation. In this paper, an

Matrix measure and application to stability of matrices and interval dynamical systems

International Journal of Mathematics and Mathematical Sciences, 2003
Using some properties of the matrix measure, we obtain a general condition for the stability of a convex hull of matrices that will be applied to study the stability of interval dynamical systems.

State geometric adjustability for interval max‐plus linear systems

IET Control Theory & Applications
This article investigates the state geometric adjustability for interval max‐plus linear systems, which means that the state vector sequence is transformed into a geometric vector sequence by using the state feedback control.
