The projectors are considered as simple but important type of matrices and operators. Their basic theory can be found in many books, among which Hal mas [177], [178] are of particular significance. The projectors or projections became an active research area in the last two decades due to ideas generated from linear algebra, statistics and various areas of algorithmic mathematics. There has also grown up a great and increasing number of projection meth ods for different purposes. The aim of this book is to give a unified survey on projectors and projection methods including the most recent results. The words projector, projection and idempotent are used as synonyms, although the word projection is more common. We assume that the reader is familiar with linear algebra and mathemati cal analysis at a bachelor level. The first chapter includes supplements from linear algebra and matrix analysis that are not incorporated in the standard courses. The second and the last chapter include the theory of projectors. Four chapters are devoted to projection methods for solving linear and non linear systems of algebraic equations and convex optimization problems.

To many, the technological aspects of projection often go unnoticed, only brought to attention during moments of crisis or malfunction. For example, when a movie theater projector falters, the audience suddenly looks toward the back of the theater to see a sign of mechanical failure. The history of cinema similarly shows that the attention to projection has been most focused when the whole medium is hanging in suspension. During Hollywood's economic consolidation in the '30s, projection defined the ways that sync-sound technologies could be deployed within the medium. Most recently, the digitization of cinema repeated this process as technology was reworked to facilitate mobility. These examples show how projection continually speaks to the rearrangement of media technology. Projection therefore needs to be examined as a pivotal element in the future of visual media's technological transition. In Practices of Projection: Histories and Technologies, volume editors Gabriel Menotti and Virginia Crisp address the cultural and technological significance of projection. Throughout the volume, chapters reiterate that projection cannot, and must not, be reduced to its cinematic functions alone. Borrowing media theorist Siegfried Zielinksi's definition, Menotti and Crisp refer to projection as the "heterogeneous array of artefacts, technical systems, and particularly visual praxes of experimentation and of culture." From this, readers can understand the performative character of the moving image and the labor of the different actors involved in the utterance of the film text. Projection is not the same everywhere, nor equal all the time. Its systems are in permanent interaction with environmental circumstances, neighboring structures, local cultures, and social economies. Thus the idea of projection as a universal, fully autonomous operation cannot hold. Each occurrence of projection adds nuance to a wider understanding of film screening technologies.

Aside from distribution theory, projections and the singular value decomposition (SVD) are the two most important concepts for understanding the basic mechanism of multivariate analysis. The former underlies the least squares estimation in regression analysis, which is essentially a projection of one subspace onto another, and the latter underlies principal component analysis, which seeks to find a subspace that captures the largest variability in the original space. This book is about projections and SVD. A thorough discussion of generalized inverse (g-inverse) matrices is also given because it is closely related to the former. The book provides systematic and in-depth accounts of these concepts from a unified viewpoint of linear transformations finite dimensional vector spaces. More specially, it shows that projection matrices (projectors) and g-inverse matrices can be defined in various ways so that a vector space is decomposed into a direct-sum of (disjoint) subspaces. Projection Matrices, Generalized Inverse Matrices, and Singular Value Decomposition will be useful for researchers, practitioners, and students in applied mathematics, statistics, engineering, behaviormetrics, and other fields.

Since the first edition of this book was published in 1996, tremendous progress has been made in the scientific and engineering disciplines regarding the use of iterative methods for linear systems. The size and complexity of the new generation of linear and nonlinear systems arising in typical applications has grown. Solving the three-dimensional models of these problems using direct solvers is no longer effective. At the same time, parallel computing has penetrated these application areas as it became less expensive and standardized. Iterative methods are easier than direct solvers to implement on parallel computers but require approaches and solution algorithms that are different from classical methods. Iterative Methods for Sparse Linear Systems, Second Edition gives an in-depth, up-to-date view of practical algorithms for solving large-scale linear systems of equations. These equations can number in the millions and are sparse in the sense that each involves only a small number of unknowns. The methods described are iterative, i.e., they provide sequences of approximations that will converge to the solution.
