This practical guide offers a beginner's introduction to understanding and using MATLAB(R). Starting with basic features, the book covers everything needed to use the program effectively, from simple arithmetic operations with scalars to creating and using arrays to three-dimensional plots and solving differential equations. Detailed images of computer screens, tutorials, worked examples, and homework questions in math, science, and engineering make mastering the program efficient and thorough.Users gain experience running MATLAN(R) with examples incorporated throughout the book.Topic explanations within framed boxes help users learn the program and its commands in an easy-to-use format.Sample programs, applications, and homework problems allows instructors to show how MATLAB(R) is used in science and engineering.Subject matter includes script files, 2-D and 3-D plotting, function files, programming (flow control), polynomials, curve fitting, interpolation, and applications in numerical analysis. Assuming no prior MATLAB experience, this clear, easy-to-read book walks readers through the ins and outs of this powerful software for technical computing. MATLAB is presented gradually and in great detail, illustrated through computer screen shots and step-by-step tutorials, and applied in problems in mathematics, science, andengineering.
