[OS X TeX] Matrices in Equations Help

[Zachary Davis]

Monday, 1 April 2002



Hello,

I was hoping that one of you might be able to help me with a 
misunderstanding about typesetting matrix equations in LaTeX.  I have 
read through the table and matrices sections of Kopka & Daly's book 
(Chapters 4 & 5), but I seem to be missing something in which teTeX 
isn't happy with.  My source looks something like the following:

\begin{equation}
\[
\left[
\begin{array}{llcl}
(\vec{e_1},\vec{e_1}) & (\vec{e_1},\vec{e_2}) & \cdots & 
(\vec{e_1},\vec{e_n})\\
(\vec{e_2},\vec{e_1}) & (\vec{e_2},\vec{e_2}) & \cdots & 
(\vec{e_2},\vec{e_n})\\
\multicolumn{4}{c}\dotfill\\
(\vec{e_n},\vec{e_1}) & (\vec{e_n},\vec{e_2}) & \cdots & 
(\vec{e_n},\vec{e_n})
\end{array} \right]

\left[
\begin{array}{c}
c_1\\
c_2\\
\vdots \\
c_n
\end{array} \right]

=


\left[
\begin{array}{c}
(\vec{f},\vec{e_1})\\
(\vec{f},\vec{e_2})\\
\vdots \\
(\vec{f},\vec{e_n})
\end{array} \right]
\]
\end{equation}

I was hoping this would typeset two matrices being multiplied by each 
other and which were equal to a third array, and of course have an 
equation number next to it.  Any help about where I went wrong would be 
appreciated.

Thanks,
