Difference between Gilbert Strang's "Introduction to Linear Algebra" and his "Linear Algebra and Its Applications"?

Quoting an answer on Quora:

Introduction to Linear Algebra is a more introductory book, whereas Linear Algebra and Its Applications assumes that the reader is already familiar with the basics of matrices and vectors. Introduction to Linear Algebra also seems to have some material introducing the abstract view of linear algebra, whereas Linear Algebra and Its Applications looks like it's mostly focusing on material that's relevant for engineering applications.
