We will use the
(discontinued) 3rd Edition of the text. That means it is no
longer available from the publisher and may not be available in our
campus bookstore, but you
can find copies on the internet. This third edition comes in two
versions, one of which is "Updated". Either of those versions is
acceptable for our course. The Updated version comes with a CD,
but we won't be using that. In any case, please note:
Don't Buy Any Edition of
Lay's Linear Algebra Book Beyond the 3rd Edition
no matter what you see at the book store or its website.
All students should order copies of the text online as soon as
possible. Everyone should have a copy of the text by the first
day of class. Just to be on the safe side, the sections we will
cover in the first chapter have been posted as course documents on
blackboard. These can be used by anyone whose book is late
arriving. PLEASE do not share these files with anyone or post
them anywhere on the internet.
You can use any of the versions of the text shown at the following
You can also search for the book by ISBN number. The isbn numbers are
provided at the amazon pages linked above.
Most of the techniques and
processes of linear algebra are tedious to carry out by hand. It
is important that you understand how these techniques work, and why
they are valid. But when you apply the techniques it is often
much more efficient to use computer software than to try to do all the
steps by hand. For this reason, we will be seeing many examples
carried out using a general purpose matrix calculator called Free
Mat. This is free software that you can
down load that from the Free Mat website:
Please install this software before the
start of classes. We will take some class time to work
through a tutorial on Free Mat. Instructions
will be handed out in class. For reference, the tutorial
instructions are also available here.
We will also be using some special
purpose interactive webpages to explore certain concepts in the
course. For row operations, we will use this webpage: http://www.dangries.com/Flash/RowReducer/RowReducer.html.
Other websites of interest can be found on the course's page of links.
