内容简介
This book shows how to derive,test and analyze numerical methods for solving differential equations,including both ordinary and partial differential equations.The objective is that students learn to solve differential equations numerically and understand the mathematical and computational issues that arise when this is done. Includes an extensive collection of exercises,which develop both the analytical and computational aspects of the material. In addition to more than 100 illustrations,the book includes a large collection of supplemental material: exercise sets,MATLAB computer codes for both student and instructor,lecture slides and movies.
