pst-func – PSTricks package for plotting mathematical functions

The package is built for use with PSTricks. It provides macros for plotting and manipulating various mathematical functions:

  • polynomials and their derivatives f(x)=an*x^n+an-1*x^(n-1)+...+a0 defined by the coefficients a0 a1 a2 ... and the derivative order;
  • the Fourier sum f(x) = a0/2+a1cos(omega x)+...+b1sin(omega x)+... defined by the coefficients a0 a1 a2 ... b1 b2 b3 ...;
  • the Bessel function defined by its order;
  • the Gauss function defined by sigma and mu;
  • Bézier curves from order 1 (two control points) to order 9 (10 control points);
  • the superellipse function (the Lamé curve);
  • Chebyshev polynomials of the first and second kind;
  • the Thomae (or popcorn) function;
  • the Weierstrass function;
  • various integration-derived functions;
  • normal, binomial, poisson, gamma, chi-squared, student’s t, F, beta, Cauchy and Weibull distribution functions and the Lorenz curve;
  • the zeroes of a function, or the intermediate point of two functions;
  • the Vasicek function for describing the evolution of interest rates; and
  • implicit functions.

The plots may be generated as volumes of rotation about the X-axis, as well.
