See Principal Pivot Transforms: Properties and Applications digit.m Given a positive integer k in decimal form, it generates vectors d, b, whose entries are the digits of the decimal and binary representations of k, respectively. hmat.m Finds, if possible, a diagonal matrix D such that AD is strictly row diagonally dominant. In other words, check if A is an H-matrix or not. This is achieved using Algorithm H found in An Iterative Criterion for H-matrices nr.m

The Reports section contains articles that report on a specific area or application. These may be shorter state-of-the-art surveys which collate results of several authors (including perhaps previously unpublished results of the writer), or longer expository articles which can serve as an introduction to a subject for people in related areas and which bring one to the frontiers of research. This section also includes book reviews and conference reports (which contain synopses of the principal talks of meetings in linear algebra.)

147. Linear Algebra Textbook Home Page By Jim Hefferon. Free download in PDF and TeX source code. Covers the material of an undergraduate first linear algebra course. http://joshua.smcvt.edu/linearalgebra/

Linear Algebra by Jim Hefferon Mathematics Saint Michael's College Colchester, Vermont USA 05439 My text Linear Algebra is free for downloading, It covers the material of an undergraduate first linear algebra course. You can use it either as a main text, or as a supplement to another text, or for independent study. What's Linear Algebra About? When I started teaching linear algebra I found three kinds of texts. There were applied mathematics books that avoid proofs and cover the linear algebra only as needed for their applications. There were advanced books that assume that students can understand their elegant proofs and understand how to answer the homework questions having seen only one or two examples. And there were books that spend a good part of the semester doing elementary things such as multiplying matrices and computing determinants and then suddenly change level to working with definitions and proofs. Each of these three types was a problem in my classroom. The applications were interesting, but I wanted to focus on the linear algebra. The advanced books were beautiful, but my students were not ready for them. And the level-switching books resulted in a lot of grief. My students immediately thought that these were like the calculus books that they had seen before, where there is material labelled `proof' that they have successfully skipped in favor of the computations. Then, by the time that the level switched, no amount of prompting on my part could convince them otherwise and the semesters ended unhappily.

The al-jabr gave us the word algebra. introduced the decimal system, rules for solving linear and quadratic equations, the word algorithm comes from his name. http://www.windows.ucar.edu/people/middle_ages/al-khwarizmi.html

Abu Ja'far al-Khwarizmi Abu Ja'far al-Khwarizmi was an Arab mathematician who lived between AD 780 and 850. At a time when the spread of ideas was difficult, al-Khwarizmi wrote a book which contained many important mathematical concepts of the Middle East. This book changed all of European mathematics, introducing the decimal system and rules for doing algebra.
