Linus Romer submitted an update to the
bezierplot
package.
Version: 1.6 2024-11-02
License: lppl1.3c
Summary description: Approximate smooth function graphs with cubic bezier splines for use with TikZ or MetaPost
Announcement text:
In the last version, functions like "sqrt(x)*sin(x)/x" created an infinite loop. This was because the recursion added new inflection points as the derivative was calculated numerically. In this version, a maximum recursion depth stops the loop. Sinh, cosh, tanh, rad, deg have been added as function types.
The package’s Catalogue entry can be viewed at https://ctan.org/pkg/bezierplot The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/luatex/latex/bezierplot/
Thanks for the upload. For the CTAN Team Petra Rübe-Pugliese

bezierplot – Approximate smooth function graphs with cubic bezier splines for use with TikZ or METAPOST
This package consists of a Lua program as well as a (Lua)LaTeX .sty file.
Given a smooth function, bezierplot returns a smooth bezier path written in TikZ notation (which also matches METAPOST) that approximates the graph of the function. For polynomial functions of degree ≤ 3 and their inverses the approximation is exact (up to numeric precision).
bezierplot also finds special points such as extreme points and inflection points and reduces the number of used points.
