# Example: Andler optimal lot-size

Published 2009-10-27 | Author: Felix Lindemann

Optimal lot-size with the Andler formula. Animated to show the influence of the k_l and k_b parameters.

Acrobat required for viewing the animation. Gnuplot required for compiling the example.

Do you have a question regarding this example, TikZ or LaTeX in general? Just ask in the LaTeX Forum.

How to get atbegshi?

• #2 Kjell Magne Fauske, May 23, 2010 at 8:40 p.m.

atbegshi is required for compatibility between hyperref and Beamer. If it is not included in TeXLive or MikTeX, you can download it from CTAN
