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.
