available libraries for linear algebra

by Mohsen Maesumi - Saturday, 16 October 2010, 12:33 AMNumber of replies: 2

Is there any linear algebra text that is supported by webwork public libraries? Do you have any experience with commercial online grading systems for introductory linear algebra? Any recommendations?

We've used Lay's Linear Algebra text at TCNJ and found that most of the Webwork problems in Linear Algebra correspond fairly well with the chapters in that text.

We have been using the existing Webwork libraries with both Nicholson's Linear Algebra and Anton's Elementary Linear Algebra. There is plenty of material available for a first-year course.
The one warning I have is to make sure that the conventions/notation/definitions used by the questions are the same as those used by your text. We have run into several circumstances where terms in Webwork are used differently than they are in the textbook (e.g. what constitutes echelon form, the definition of characteristic polynomial, the method for LU-decomposition).
