Confusing notation

The linear algebra book I'm reading talks about "the matrix [A|b]", in the context of the linear system Ax = b. What does this notation (the two symbols separated by a pipe enclosed in brackets) mean? I've tried looking in the notation index, but I can't find it.

Re: Confusing notation

I believe that refers to an augmented matrix.
