To get started, let's try to get a matrix into the computer, and do
something with it. You can enter the matrix
like this
A = [1,2,3;4,5,6]

Notice that a semicolon is used to separate the two rows. You can enter the
column vector
like this:
B = [7;8]

Now suppose you want the augmented matrix . You can enter it like
so:
[A,B]

Notice the use of a comma to tack on a new *column*. If you were
appending a *row* to a matrix, you'd use a semicolon instead.
