Graphics, Figures & Tables ⇒ A too big matrix

[helllo]

Hi guys, I was wondering if it is possible to fit a slightly too big matrix using some command ?

Thanks!

Hi,

you can

• Decrease the font size, for example by \small
• Make the space between columns and rows smaller, for example by using \arraystretch
• Use \resizebox or \scalebox of the graphicx package

Hey,

thanks for the reply.

The first one doesn't work (\small is still too big, with \tiny it almost works but then it's quite "tiny").

I'm now trying to figure out how to use \arraystretch

[*] Make the space between columns and rows smaller, for example by using \arraystretch

How does this work ?
I tried:

Code: Select all

\renewcommand{\tabcolsep}{85mm}
\renewcommand{\arraystretch}{10}

with different numbers but it doesn't change anything.
Any idea?

\arraystretch can be redefined to be smaller than 1, such as 0.9.

\tabcolsep is a length, so adjust it this way:

Code: Select all

\setlength{\tabcolsep}{1pt}

Hey, thanks but it still doesn't work.
I think I may be doing something wrong, here is what i write:

Code: Select all

\begin{pmatrix}
\setlength{\tabcolsep}{1pt}
\renewcommand{\arraystretch}{0.9}

then write the elements of the matrix and then close with

Code: Select all

\end{pmatrix}

I'm saying it's not woking cause each time I change the numbers (for tabolsep and arraystrtch) nothing happens

[Stefan Kottwitz]

Adjust the value before you start the matrix, such as:

Code: Select all

\[
  \setlength{\arraycolsep}{2pt}
  \renewcommand{\arraystretch}{0.8}
  \begin{pmatrix}
    ...
  \end{pmatrix}
\]

\]

this works but it's still not enough.
Is it possible to reduce the font just for the matrix ?
Thanks!

[Stefan Kottwitz]

For example, temporarily leaving math mode for changing the font size:

Code: Select all

$M = \mbox{\footnotesize$
  \begin{pmatrix}
    ...
  \end{pmatrix}$}$

You can use also \tiny, \scriptsize or \small instead.
