This paper deals with the description of a new method for calculating the functional output-
controllability. It is computed by means of the rank of a certain constant matrix which can be …

StratiGraph, a Java‐based tool for computation and presentation of closure hierarchies of
Jordan and Kronecker structures is presented. The tool is based on recent theoretical results …

In this paper, by extending the controllability and Brunovsky indices for a matrix pair to a
matrix quadruple, three kinds of indices, say, the invertibility indices, the left invertibility …

In this work we make a detailed look at the algebraic structure of convolutional codes using
techniques of linear systems theory. In particular we study the input-state-output …

Computing the fine-canonical-structure elements of matrices and matrix pencils are ill-posed
problems. Therefore, besides knowing the canonical structure of a matrix or a matrix pencil …

In this paper we consider two models of concatenated convolutional codes from the
perspective of linear systems theory. We present an input-state-output representation of …

We consider triples of matrices (E, A, B), representing singular linear time invariant systems
in the form, with E, A∈ Mn (C) and B∈ Mn× m (C), under proportional and derivative …

We consider triples of matrices (E, A, B), representing singular linear time invariant systems
in the form Ex (t)= Ax (t)+ Bu (t), with E, A∈ Mp× n (C) and B∈ Mn× m (C), under the …

Information is such a valuable good of our time. Given that the transmission of information
has always been subject to precision problems, knowing the obstacles existing between the …

Specific algorithms, such as those involving the supremal of the invariant subspaces
contained in a suitable subspace, are known to be able to test whether a Disturbance …
