A textbook that stresses both practical computation and theoretical principles, and centers on the principal topics of the first three chapters: matrix theory and systems of linear equations, elementary vector-space concepts, and the eigenvalue problem. This core material can be used for a brief (ten-week) course at the late- freshman/sophomore level. There is enough additional material in chapters 4-7 for a more advanced or more leisurely paced course. This edition (2nd, 1989) adds supplementary exercises at the end of each chapter, examples that illustrate the use of linear algebra software, new examples and exercises that illustrate applications of linear algebra, and a number of historical notes.
