| Description: | 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). pst-math 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.
