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 :-) - - ----------------------------------------------------------------------
