An Engineer's Guide to Numerical Analysis To properly function in today's work environment, engineers require a working familiarity with numerical analysis. This book provides that necessary background, striking a balance between analytical rigor and an applied approach focusing on methods particular to the solving of engineering problems. An Introduction to Numerical Analysis for Electrical and Computer Engineers gives electrical and computer engineering students their first exposure to numerical analysis and serves as a refresher for professionals as well. Emphasizing the earlier stages of numerical analysis for engineers with real-life solutions for computing and engineering applications, the book: <ul> <li>Forms a logical bridge between first courses in matrix/linear algebra and the more sophisticated methods of signal processing and control system courses</li> <li>Includes MATLAB®-oriented examples, with a quick introduction to MATLAB for those who need it</li> <li>Provides detailed proofs and derivations for many key results</li> </ul> Specifically tailored to the needs of computer and electrical engineers, this is the resource engineers have long needed in order to master an area of mathematics critical to their profession.
