See the review of the fifth edition. The main change in this edition is the rearrangement of some of the material. Certain concepts (linear combination, closure, basis, dimension) are introduced earlier in order to prepare students for the more abstract approach introduced in chapter four. The hope is to improve "the uniformity of the level of the material throughout the course." A few new topics and new applications have also been added.
