To overcome the problems of system theory and network theory over real field, this book uses matrices over the field
F(z) of rational functions in multi-parameters describing coefficient matrices of systems and networks and makes systems and network description over
F(z) and researches their structural properties: reducible condition of a class of matrices over
F(z) and their characteristic polynomial; type-1 matrix and two basic properties; variable replacement conditions for independent parameters; structural controllability and observability of linear systems over
F(z); separability, reducibility, controllability, observability and structural conditions of networks over
F(z), and so on. This book involves three subjects: systems, networks and matrices over
F(z), which is an achievement of interdisciplinary research.
Readership: For researchers, graduate students, and engineers in the field of electrical engineering, electronics, automation and applied mathematics (matrix theory).
