Dear Herbert,
Unfortunately, I could not get it work.
Here is my code

\centerline{\bf Table I::DCT Matrix (N=8)}% Heading
$\begin{vmatrix}C(0)\\C(1)\\C(2)\\C(3)\\C(4)\\C(5)\\C(6)\\C(7) \end{vmatrix} = \begin{vmatrix} 1.000& 1.000& 1.000& 1.000& 1.000& 1.000& 1.000& 1.000 \\ 0.981& 0.831& 0.556& 0.195& -0.195& -0.556& -0.831& -0.981 \\ 0.924& 0.383& -0.383& -0.924& -0.924& -0.383& 0.383& 0.924 \\ 0.831& -0.195& -0.981& -0.556& 0.556& 0.981& 0.195& -0.831 \\ 0.707& -0.707& -0.707& 0.707& 0.707& -0.707& -0.707& 0.707 \\ 0.556& -0.981& 0.195& 0.831& -0.831& -0.195& 0.981& -0.556 \\ 0.383& -0.924& 0.924& -0.383& -0.383& 0.924& -0.924& 0.383 \\ 0.195& -0.556& 0.831& -0.981& 0.981& -0.831& 0.556& -0.195 \end{vmatrix} \quad \begin{vmatrix}f(0)\\f(1)\\f(2)\\f(3)\\f(4)\\f(5)\\f(6)\\f(7) \end{vmatrix}$

to get it working.

With regards,
