<p>I was wondering if anyone knew how I could produce upright greek letters on stats.SE? In my documents, I usually do this using the $\LaTeX$ <a href="http://www.ctan.org/pkg/upgreek" rel="nofollow noreferrer">upgreek package</a>.</p>

<h3>Edit</h3>

<p>I am uploading an image of what I hope the upright greek letters look like. The $\LaTeX$ code to produce this document is included below.</p>

<pre><code>\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{amsmath, upgreek, booktabs, tabularx, colortbl}
\usepackage[active, tightpage]{preview}
\begin{document}
\begin{table}[htbp]
\begin{preview}
\begin{tabular}{ccc}
\toprule
 &amp; Deterministic &amp; Non-deterministic \\
\midrule
Scalar &amp; $\alpha, \beta, \gamma$ &amp; $X, Y, Z$ \\
Vector &amp; $\boldsymbol{\alpha}, \boldsymbol{\beta}, \boldsymbol{\gamma}$ &amp; $\boldsymbol{X}, \boldsymbol{Y} \boldsymbol{Z}$ \\
Matrix &amp; \cellcolor{blue!25}$\boldsymbol{\upalpha}, \boldsymbol{\upbeta}, \boldsymbol{\upgamma}$ &amp; $\mathbf{X}, \mathbf{Y}, \mathbf{Z}$ \\
\bottomrule
\end{tabular}
\end{preview}
\end{table}
\end{document}
