Page Layout ⇒ Matrices on same line

[david__taylor]

I have two 6x6 matrices in a latex document, and I want them to appear on the same line in the document. At the moment, the second one just sits below the first one. Can anyone help?

Thanks,

David


This is the code I have for the matrices:


\[ \left( \begin{array}{cccccc}
1 & 0 & 0 & 0 & 0 & 0 \\
0 & 1 & 0 & 0 & 0 & 0 \\
0 & 0 & 1 & 0 & 0 & 0 \\
0 & 0 & 0 & 1 & 0 & 0 \\
0 & 0 & 0 & 0 & 1 & 0 \\
0 & 0 & 0 & 0 & 0 & 1
\end{array} \right)\]


\[ \left( \begin{array}{cccccc}
1 & 0 & 0 & 0 & 0 & 0 \\
1 & 0 & 0 & 0 & 0 & 0 \\
1 & 0 & 0 & 0 & 0 & 0 \\
1 & 0 & 0 & 0 & 0 & 0 \\
0 & 1 & 0 & 0 & 0 & 0 \\
0 & 0 & 1 & 0 & 0 & 0
\end{array} \right)\]

Hi,

you could try something like the following:

Code: Select all

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{equation*}
\left( \begin{array}{cccccc}
  1 & 0 & 0 & 0 & 0 & 0 \\
  0 & 1 & 0 & 0 & 0 & 0 \\
  0 & 0 & 1 & 0 & 0 & 0 \\
  0 & 0 & 0 & 1 & 0 & 0 \\
  0 & 0 & 0 & 0 & 1 & 0 \\
  0 & 0 & 0 & 0 & 0 & 1
\end{array} \right)
\left( \begin{array}{cccccc}
  1 & 0 & 0 & 0 & 0 & 0 \\
  1 & 0 & 0 & 0 & 0 & 0 \\
  1 & 0 & 0 & 0 & 0 & 0 \\
  1 & 0 & 0 & 0 & 0 & 0 \\
  0 & 1 & 0 & 0 & 0 & 0 \\
  0 & 0 & 1 & 0 & 0 & 0
\end{array} \right)
\end{equation*}

\end{document}

Thanks for the reply.

Do you know how to space them out across the page more? I want the first one on the left, and the next one on the right of the page (maybe with a bullet point before each or something like '(a)' before the first one and '(b)' before the 2nd one.???

You can modify gmedina's code slightly and put each matrix as a single element of a larger array, with (a) and (b) in the neighbouring cells and use \hspace{} to create a gap between the two, as big or small as you wish.

Code: Select all

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{equation*}
\begin{array}{cccc}
(a)&
\left( \begin{array}{cccccc}
  1 & 0 & 0 & 0 & 0 & 0 \\
  0 & 1 & 0 & 0 & 0 & 0 \\
  0 & 0 & 1 & 0 & 0 & 0 \\
  0 & 0 & 0 & 1 & 0 & 0 \\
  0 & 0 & 0 & 0 & 1 & 0 \\
  0 & 0 & 0 & 0 & 0 & 1
\end{array} \right)\hspace{0.2\textwidth}&
(b)&
\left( \begin{array}{cccccc}
  1 & 0 & 0 & 0 & 0 & 0 \\
  1 & 0 & 0 & 0 & 0 & 0 \\
  1 & 0 & 0 & 0 & 0 & 0 \\
  1 & 0 & 0 & 0 & 0 & 0 \\
  0 & 1 & 0 & 0 & 0 & 0 \\
  0 & 0 & 1 & 0 & 0 & 0
\end{array} \right)
\end{array}
\end{equation*}

\end{document}

Code: Select all

\documentclass[11p4,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}

\begin{document}
  \begin{alignat*}{2}
    (a)\quad &
    \begin{pmatrix}
      1 & 0 & 0 & 0 & 0 & 0 \\
      0 & 1 & 0 & 0 & 0 & 0 \\
      0 & 0 & 1 & 0 & 0 & 0 \\
      0 & 0 & 0 & 1 & 0 & 0 \\
      0 & 0 & 0 & 0 & 1 & 0 \\
      0 & 0 & 0 & 0 & 0 & 1
    \end{pmatrix} \qquad&
    (b)\quad &
    \begin{pmatrix}
      1 & 0 & 0 & 0 & 0 & 0 \\
      1 & 0 & 0 & 0 & 0 & 0 \\
      1 & 0 & 0 & 0 & 0 & 0 \\
      1 & 0 & 0 & 0 & 0 & 0 \\
      0 & 1 & 0 & 0 & 0 & 0 \\
      0 & 0 & 1 & 0 & 0 & 0
    \end{pmatrix}
  \end{alignat*}
\end{document}

An alternative to localghost's suggestion:

Code: Select all

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{flalign*}
  (a)\quad &
  \begin{pmatrix}
    1 & 0 & 0 & 0 & 0 & 0 \\
    0 & 1 & 0 & 0 & 0 & 0 \\
    0 & 0 & 1 & 0 & 0 & 0 \\
    0 & 0 & 0 & 1 & 0 & 0 \\
    0 & 0 & 0 & 0 & 1 & 0 \\
    0 & 0 & 0 & 0 & 0 & 1
  \end{pmatrix} \qquad&
  (b)\quad &
  \begin{pmatrix}
    1 & 0 & 0 & 0 & 0 & 0 \\
    1 & 0 & 0 & 0 & 0 & 0 \\
    1 & 0 & 0 & 0 & 0 & 0 \\
    1 & 0 & 0 & 0 & 0 & 0 \\
    0 & 1 & 0 & 0 & 0 & 0 \\
    0 & 0 & 1 & 0 & 0 & 0
  \end{pmatrix}
\end{flalign*}

\end{document}
