Chapter Chapter 1 in Numerical Linear Algebra: Theory and Applications, 2017, pp 1-54 from Springer

Abstract: Abstract In this chapter we provide the necessary background from the theory of complex numbers. Then we describe the basic properties of polynomials and their roots. We introduce the concept of determinants, establish their properties, and present the basic theory of systems of linear algebraic equations with nonsingular matrices. The main types of rectangular matrices are described.
