PostScript operators and Reverse Polish Notation for plotting using PSTricks

Question

I know that the PSTricks packages for plotting, pst-plot and pst-3dplot, use PostScript operators and Reverse Polish Notation. Is there a comprehensive list of all the operators available, with a guide on such notation?

Answer 1

You can find them in a manual of PostScript language.

See PostScript Language Reference, third edition

And for convinience, The PostScript Language Tutorial and Cookbook and PostScript Language Program Design are easier to read. You can find them at Adobe PostScript SDK Archive

Maybe you have known that, PSTricks can also use infix expression to plot functions, with help of algebraic=true. For example:

\documentclass{article}
\usepackage{pst-plot}
\begin{document}
\psset{algebraic=true}
\begin{pspicture}(-4,-1.5)(4,1.5)
\psaxes(0,0)(-3.5,-1.5)(3.5,1.5)
\psplot[linecolor=blue]{-3.14}{3.14}{sin(x)}
\end{pspicture}
\end{document}

Supported functions:

+ - * / ^
sin, cos, tan, acos, asin (in radians)
log, ln
ceiling, floor, truncate, round, sqrt, abs, fact (for the factorial)
Sum (for building sums)
IfTE (for an easy case structure)

See manual pst-news10 for details.

Answer 2

The language reference is a bit heavyweight. This is the reference I use: Alphabetic list of PostScript commands. Comprehensive, yet browsable. In case that reference goes away, one can likely find a mirror searching for page titles containing Postscript Level 2.
