Hi all,

How could I type set this matrix like thing?

Thanks!

Would you mind clarifying what is being attempted?
My initial understanding, when I looked at the image, is that there are four columns and three rows. The first bracket applies to the first two rows, the second to the last two rows, and the final bracket applies to all three rows together.

I am not certain what the purpose is for it, or if this is correct. Can you elaborate a bit?

Hi there,

Your understanding is correct.
This 'wired' expression came from my lecture notes, where
the first column are the means from some experiment.
The brackets 'says' that the difference is significant at certain level.

I found that I may need to use bigdelim package,
But i haven't quite figured out how to use it.

Thanks.

It may depend on how fussy you are. The following gives a rough and ready version of your "matrix like thing":

Code: Select all

\documentclass{article}
\usepackage{multirow}
\begin{document}

\begin{tabular}{rcr@{}lc}
      & 5\% & \multicolumn{2}{c}{1\%}                         & 0.1\% \\
17.17 &     &\multirow{2}{*}{\Big\}} &                        & \multirow{3}{*}{\Bigg\}}\\
20.20 &     &                        &\multirow{2}{*}{\Big\}} & \\
23.04 &     &                        &                        & \\
\end{tabular}

\end{document}

This isn't perfect, but it may be good enough. (I wasn't very sure if the dots in the scan were part of the construction or just a byproduct of the scanning process. I also wasn't sure that a tabular would work in the larger context.)

(EDIT: Oops, 20.20 should 20.29, but that's easily fixed.)

That's a nice and easy way to 'cheat'.

Thanks!
