File talk:Plot 4xx4.png

Hi. Great image. Thx. Could you give here source code ? --Adam majewski (talk) 19:41, 8 December 2008 (UTC)


 * Yes. It requires mpmath and matplotlib.

from mpmath import * cplot(lambda x: sign(4**x-x**4), [-20, 20], [-20, 20], points=100000, verbose=1)

Thx. I didn't know these programs. Looks great. I will try it.

I have put sorce code on file page ( if you don't mind it ).

I'm using maxima and gnuplot. Can you compare it with your programs ?

If you like you can :
 * move it to commons ,
 * make new category ( in commons) like in gnuplot and maxima case :
 * Category:Gnuplot_diagrams
 * Category:Created with Maxima (software)
 * ad new categories to your's image page

Do you know Visualizing Conformal Maps by Michael J. Gruber ? --Adam majewski (talk) 15:58, 9 December 2008 (UTC)


 * I don't see a need to upload this to commons since it was just intended to answer a question on the reference desk. I'm not too familiar with gnuplot, sorry. I might have seen that web page before. Fredrik Johansson 16:47, 9 December 2008 (UTC)
