MATLAB for Engineers, 3rd Edition

MATLAB for Engineers, 3e, is ideal for Freshman or Introductory courses in Engineering and Computer Science. With a hands-on approach and focus on problem solving, this introduction to the powerful MATLAB computing language is designed for students with only a basic college algebra background. Numerous examples are drawn from a range of engineering disciplines, demonstrating MATLAB’s applications to a broad variety of problems. This book is included in Prentice Hall’s ESource series. ESource allows professors to select the content appropriate for their freshman/first-year engineering course. Professors can adopt the published manuals as is or use ESource’s website www.prenhall.com/esource to view and select the chapters they need, in the sequence they want. The option to add their own material or copyrighted material from other publishers also exists.
