This text focuses on theory algorithms and MATLABÂ® implementation. Each chapter presents theoretical background with extensive mathematical treatment as well as algorithmic structures and data manipulation that emphasize matrix and linear algebra-based architecture and system design. The chapters also include MATLAB exercises and sample programs to help readers who lack a sound background in engineering and mathematics. The authors also provide actual classroom-based summaries that are designed to be used as lecture notes. The accompanying CD-ROM and supplementary website features MATLAB programs, PowerPoint presentations, and lecture material for instructors.
