CTAN Update: bezierplot

Date: June 11, 2018 5:23:31 PM CEST
Linus Romer submitted an update to the bezierplot package. Version: 1.1 2018-06-10 License: lppl1.3c Summary description: Approximate smooth function graphs with cubic bezier splines for use with TikZ or MetaPost Announcement text:
Three bugs have been removed: x^4+1 did not work because the function do_parameters_fit did not check the parameters for being not nan nor huge nor -huge x^6+1 did not work because the numerical derivative 0 led to several local extrema just next to each other empty graphs should now not throw any errors anymore New feature: xmin, xmax, ymin, ymax may now be computable expressions, hence you can type now bezierplot "sin(x)" -pi pi -3*7 2*e+1

bezierplot – Approximate smooth function graphs with cubic bezier splines for use with TikZ or

This package consists of a Lua program as well as a (Lua) .sty file.

Given a smooth function, bezierplot returns a smooth bezier path written in TikZ notation (which also matches ) 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.
