Approximate smooth function graphs with cubic bezier splines for use with TikZ or MetaPost
Description
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.
