a) take out the \[ and \]. I don't know what they're for.
b) no blank lines allowed in the middle of equations
c) Here it is fixed.
\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}
