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:

$$$\left[ \begin{array}{llcl} (\vec{e_1},\vec{e_1}) & (\vec{e_1},\vec{e_2}) & \cdots & (\vec{e_1},\vec{e_n})\\ (\vec{e_2},\vec{e_1}) & (\vec{e_2},\vec{e_2}) & \cdots & (\vec{e_2},\vec{e_n})\\ \multicolumn{4}{c}\dotfill\\ (\vec{e_n},\vec{e_1}) & (\vec{e_n},\vec{e_2}) & \cdots & (\vec{e_n},\vec{e_n}) \end{array} \right] \left[ \begin{array}{c} c_1\\ c_2\\ \vdots \\ c_n \end{array} \right] = \left[ \begin{array}{c} (\vec{f},\vec{e_1})\\ (\vec{f},\vec{e_2})\\ \vdots \\ (\vec{f},\vec{e_n}) \end{array} \right]$$$

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,
