Herbert Voß submitted an update to the pst-func package. Version: 1.01 License: lppl Summary description: PSTricks package for plotting mathematical functions Announcement text:
..... pst-func.tex - added \psNonCentralTDist (noncentral Student's distribution) - fix \psBessel: use toDeg instead of k - set algebraic=false ..... pst-func.pro - added /ConfHyperFunc (Confluent Hypergeometric Function of the First Kind, needed by \psNonCentralTDist)
The package’s Catalogue entry can be viewed at https://ctan.org/pkg/pst-func The package’s files themselves can be inspected at https://mirrors.ctan.org/graphics/pstricks/contrib/pst-func/

## 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.
