MATLAB: An Introduction with Applications

More college students use Amos Gilat’s MATLAB: An Introduction with Applications than any other MATLAB textbook. This concise book is known for its just-in-time learning approach that gives students information when they need it. The 6th Edition gradually presents the latest MATLAB functionality in detail. The book includes numerous sample problems in mathematics, science, and engineering that are similar to problems encountered by new users of MATLAB. MATLAB: An Introduction with Applications is intended for students who are using MATLAB for the first time and have little or no experience in computer programming. It can be used as a textbook in first-year engineering courses or as a reference in more advanced science and engineering courses where MATLAB is introduced as a tool for solving problems.

About the Author :
Amos Gilat, Ph. D., is a Mechanical Engineering Professor at the Ohio State University. Dr. Gilat's main research interests are in the area of plasticity, specifically, in developing experimental techniques for testing materials over a wide range of strain rates and temperatures and in investigating constitutive relations for viscoplasticity. The thrust of his research is on developing correlation between observed material response on the continuum scale and the actual deformation process on the microscopic scale. Dr. Gilat's research has been supported by the National Science Foundation, Department of Energy, Department of Defense, and Ford Motor Company.
