The Introduction consists of three sections that establish the general setting and give background information that is useful to know before starting to read the other chapters. In particular, it presents an overview of a typical solution process of problems in computational sciences and engineering consisting of modelling, discretisation, and computation. Here and in many other places in the book we argue that computations should always be considered in the context of the overall solution process, which is of utmost importance when computations are performed iteratively. The second section provides a brief overview of the historical evolution of topics related to the modern field of Krylov subspace methods. This also helps in putting the historical notes later in the book into their proper context. The Introduction ends with the specification of the main notation.
