Pages Latex Equation Editor: Augmented Matrices
I'm a novice in LateX and wanted to make an augmented matrix on Pages.
So far this is what I have:
(A|b)=
\begin{pmatrix}
a_{11} & a_{12} & b_1\\
a_{21} & a_{22} & b_2\\
a_{31} & a_{32} & b_3\\
\end{pmatrix}
I can't seem to get the vertical line.
Please help.
Thanks.
