This paper considers the backward error analysis of an approximate eigenpair of blockwise structured matrix pencils that becomes an exact eigenpair of an ...

Matrix polynomials and moment problems are significant areas of study in mathematics, particularly in the fields of control theory, numerical analysis, and probability. Matrix polynomials are ...

Matrix splitting iteration methods have emerged as potent tools in addressing complementarity problems, which frequently arise in optimisation, economics and engineering applications. These methods ...

A common problem faced by teachers of research methods is the difficulty of providing students with an integrated view of theory, methods, and statistics. In this paper, I offer a visual device which ...
