name pst-math category Package shortdesc Enhancement of postscript math operators to use with pstricks longdesc Postscript lacks a lot of basic operators such as tan, acos, asin, longdesc cosh, sinh, tanh, acosh, asinh, atanh, exp (with e base). cos, sin longdesc give result in degrees. pst-math provides all those operators in a longdesc header file pst-math.pro with wrappers pst-math.sty and pst- longdesc math.tex. In addition, sinc, gauss, gammaln and bessel are longdesc implemented (only partially for the latter). pst-math is designed longdesc essentially to work with pst-plot but can be used in whatever PS longdesc code (such as pstricks SpecialCoor "!", useful to put labels). longdesc This work is in progress! PS is limited to single precision so longdesc complex operators like gammaln can give erroneous results. longdesc [description copied from TeX Catalogue]
