and explores key applications in communication and signal processing, neural networks and pattern recognition, and optics and image processing. This book: Reviews the fundamentals of vector space theory Covers principles and applications of vector space projections in general, and projections onto convex sets in particular Provides real-world examples solvable on PCs and modest workstations Features more than 100 illustrations Includes end-of-chapter exercises and references. This extremely useful reference for practicing engineers, scientists, and educators can also be used for graduate-level study in science, mathematics, and engineering. Portions of the book have been used as material in short courses on applications of vector space projections.
