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.

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.

Eadweard Muybridge is among the seminal originators of the contemporary world's visual form, with its concentrated image-sequences of bodies in movement and its ocular obsessions. This book examines an almost unknown dimension of Muybridge's work, as a moving-image projectionist, who toured Europe's cities to enthral beyond-capacity audiences with unprecedented projections and who built a moving-image auditorium - long before cinemas were created - in which to project his work at the 1893 Chicago World's Columbian Exposition. That final invention of Muybridge's was both an all-engulfing catastrophe and the vital precursor for the following century's worldwide manias for projection. Based on entirely new research into Muybridge's travels, audiences, auditoria and projectors, this book explores his initiating role in moving-image projection and also maps Muybridge's driving inspiration for subsequent artists and filmmakers preoccupied with the volatile entity of projection, from 1890s Berlin to contemporary Japan, via further spectacular World's Exposition events and cinemas' overheated projection-boxes. The book looks closely at the enigmatic figure of the moving-image projectionist, from its origins in Muybridge's experiments, across glass, celluloid and digital projections, to the contemporary moment. Moving-image projection formed a crucial determinant in the imagining of new corporealities and new urban spaces, through its irrepressible capacity to envision future bodies and cities. The cinema projectionist - a solitary figure of compulsion and restlessness, inhabiting a profession touched with the multiple addictions and deaths of the moving image - was once a pivotal presence for global cinema audiences but is now consigned to near-obsolescence. The book investigates contemporary urban projections as aberrant manifestations derived from Muybridge's first conjurations of projection's power for its spectators. Throughout, the book interrogates.
