I'm using LaTeX to show the butterfly visualization of fast Fourier transformation and I'm stuck at drawing the matrix.
I want something like this:
i.e. if I have a vector of length 8, in the next column (after the equal sign), I want two matrices each of length 4 on the same column one below the other, how can I achieve this?
\documentclass{article}
\begin{document}
\left[ \begin{array}{ccc}
1 \\
0 \\
0 \\
0 \\
3 \\
0 \\
0 \\
0 \\
\end{array} \right]
\end{document}

This requires some manual adjustment, but if you don't have too many of these butterflies, it might be sufficient:
The new optional argument to
\vdots
tells how many dots are to be printed.
