Linear algebra continues to be one of the most useful courses in undergraduate mathematics, science and engineering, providing essential tools for industrial scientists. This book gives a careful presentation of the basic concepts of linear algebra as a coherent part of mathematics, and illustrates its practical power through a variety of interesting applications new to this second edition.  This treatment differs from competitors in its emphasis and integration of computational skills and mathematical abstractions.This clean and elegant presentation requires only a sound foundation in calculus. It is well balanced as a strong mathematical first course for well-prepared and motivated students or as an excellent second course in the theory and applications of linear algebra. Selected Answers and Hints make this a useful text for self-study.
