CTAN up­date: bezier­plot

Date: July 24, 2018 11:05:22 AM CEST
Li­nus Romer sub­mit­ted an up­date to the bezier­plot pack­age. Ver­sion num­ber: 1.2 2018-07-23 Li­cense type: lp­pl1.3c Sum­mary de­scrip­tion: Ap­prox­i­mate smooth func­tion graphs with cu­bic bezier splines for use with TikZ or Me­taPost An­nounce­ment text:
Changes: - new fea­ture: ymin and ymax may be 'huge' (which is the nu­mer­i­cal in­fin­ity in lua) - new fea­ture: fixed sam­ples may be set (if sam­ples < 2, bezier­plot chooses sam­ples at the best points as usual) - the pre­ci­sion has been in­creased (more in­vis­i­ble sam­ples, more dig­its) - more pre­cise and faster com­pu­ta­tions for affine, quadratic, cu­bic func­tions and their in­verses - no re­dun­dandt points af­ter round­ing any­more

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.
