Matrices and matrix operations are studied and applied in many areas such as engineering,
natural and social sciences. Books written on these topics include Berman et al.(1989) …

This paper is concerned with a long list of matrix products for partitioned and non-partitioned
matrices, including Kronecker, Khatri–Rao of first kind, Hadamard, Tracy–Singh, Khatri–Rao …

The weighted least-squares solutions of coupled singular matrix equations are too difficult to
obtain by applying matrices decomposition. In this paper, a family of algorithms are applied …

Matrix and matrix differential equations play an important role in system theory, control
theory, stability theory of differential equations, communication systems and many other …

In Kronecker products works, matrices are sometimes regarded as vectors and vectors are
sometimes made in to matrices. To be precise about these reshaping we use the vector and …

In this paper, we generalize the time-varying descriptor systems to the case of fractional
order in matrix forms. Moreover, we present the general exact solutions of the linear singular …

After receiving a report from a reader, the Editor-in-Chief consulted a third party expert and
an Associate Editor of the journal. The response from the author has been considered …

We propose a model reduction technique for quadratic-bilinear descriptor systems. The
approach involves approximating the system by a bilinear descriptor system using Carleman …

The aim of this article is to present fractional versions of the Hadamard type inequalities for
exponentially (s, m)-convex functions via k-analogue of Riemann-Liouville fractional …

In this paper, the result are established in the following four ways: First, we present a general
representation for the weighted Drazin inverse Ad, W of an arbitrary rectangular matrix A∈ …
