Hi and welcome to our little community.

Can you give any information where this command is coming from and what you are trying to do?

Code: Select all

% arara: xelatex
\documentclass{article}
\usepackage{pst-plot}
\usepackage{tikz}
\begin{document}
\begin{pspicture}(-4,-4)(4,4)
	\psparabola(2,4)(0,0)
\end{pspicture}
\begin{tikzpicture}
	  \draw (0,0) parabola (1.5,2.25) ;
	  \draw (0,0) parabola (-1.5,2.25) ;
\end{tikzpicture}
