# CTAN has a new package: pst-math

Date: June 24, 2004 1:40:45 PM CEST

A new package has been installed on tug.ctan.org and should make its
way to your favorite mirror real soon.
Thanks for the upload,
Jim Hefferon

The following information was provided by the package's contributor.
Name of contribution: pst-math
Author's name: Christophe Jorssen
Location on CTAN: graphics/pstricks/contrib/pst-math
Summary description: Enhancement of postscript math operators to use
with pstricks
License type: lppl
Announcement text given by the package's contributor:
- - ----------------------------------------------------------------------
Postscript lacks a lot of basic operators such as tan, acos, asin, cosh,
sinh, tanh, acosh, asinh, atanh, exp (with e base). Also, cos and sin
give result in degrees.
pst-math provides all those operators in a header file pst-math.pro with
wrappers pst-math.sty and pst-math.tex.
In addition, sinc, gauss, gammaln and bessel are implemented (only
partially for the latter). pst-math is designed essentially to work
with pst-plot but can be used in whatever PS code (such as pstricks
SpecialCoor "!", useful to put labels).
This work is in progress! PS is limited to single precision so complex
operators like gammaln can give erroneous results. Any help on
implementing double precision math in PS would be highly appreciated :-)

##
pst-math – Enhancement of PostScript math operators to use with PSTricks

PostScript lacks a lot of basic operators such as tan, acos,
asin, cosh, sinh, tanh, acosh, asinh, atanh, exp (with e base).
Also (oddly) cos and sin use arguments in degrees.

Pst-math provides all those operators in a header file
`pst-math.pro` with wrappers `pst-math.sty`
and `pst-math.tex`.

In addition, sinc, gauss, gammaln and bessel are implemented
(only partially for the latter). The package is designed
essentially to work with pst-plot
but can be used in whatever PS code (such as PSTricks `SpecialCoor
"!"`, which is useful for placing labels).

The package also provides a routine SIMPSON for numerical
integration and a solver of linear equation systems.
