name pst-func category Package shortdesc PSTricks package for plotting mathematical functions. longdesc pst-func is a package built for use with PSTricks. It provides longdesc macros for plotting various mathematical functions. Polynomials longdesc and their derivatives $f(x)=an*x^n+an-1*x^(n-1)+...+a0$ defined by longdesc the coefficients a0 a1 a2 ... and the derivative order; the longdesc Fourier sum f(x) = a0/2+a1cos(omega x)+...+b1sin(omega x)+... longdesc defined by the coefficients a0 a1 a2 ... b1 b2 b3 ...; the Bessel longdesc function defined by its order; and the Gauss function defined by longdesc sigma [description copied from TeX Catalogue]
