A MATLAB companion for multivariable calculus

Jeffery Cooper012187625X, 9780121876258, 9780080489360

Designed for a course in multivariable calculus, this book provides a collection of MATLAB programs and exercises, along with basic concepts, computations, and graphics. Chapters focus on the command line, mfiles, vectors, curves, functions of two and three variables, solving equations, optimization, multiple integrals, scalar integrals, and electrostasis and fluid flow, Exercises include applications to economics, physics, engineering, and biology. Cooper teaches mathematics at the University of Maryland.
