    Matrices
In summary, to write matrices in the Gummi latex editor, you can use the extension from amslatex called "pmatrix". However, if the syntax used in the forum does not work when used in Gummi, you can add \usepackage{amsmath} in the preamble of your tex file to make it work. This package also has many other useful extensions and is recommended for use in most documents. You can refer to the ftp://ftp.ams.org/pub/tex/doc/amsmath/amsldoc.pdf for more information.

What are some examples of writing matrices in the Gummi latex editor? Something about the syntax used on the forum doesn't work for me when used in Gummi.

Can you show what you tried that doesn't work?

This example doesn't work when the underlying LaTex is pasted into the Gummi editor:
\begin{pmatrix} 1 & 0 \\ -1 & 1 \end{pmatrix}

pmatrix is an extension from amslatex. In the preamble of your tex file, add

\usepackage{amsmath}

and it will work. There are many useful extensions in amsmath and I use it in almost all my documents. See the ftp://ftp.ams.org/pub/tex/doc/amsmath/amsldoc.pdf.

Thank you DrClaude.
\usepackage{amsmath} in the preamble makes things behave as expected.
