w

I'm not a Maxima user but this seems strange:

 w:rectform(ev(R*exp(2*%pi*%i*t))),
 /* */
 last_z:z,
 z:Psi_n(r,t,last_z,R_max), /* z=Psi_n(w) */

Set w - then don't use it! The comment clearly says 'z=Psi_n(w)' but having calculated w then last_z is set to z? Can you clarify this please. — Preceding unsigned comment was added by 31.48.216.195 (talk) 08:41, 28 January 2017 (UTC)

I'm glag that you have found it interesting. Yes, you are right but to anwser your question I should go back to the code and run it with " w:rectform(ev(R*exp(2*%pi*%i*t)))," commented out. I will try to check it out and give more precisely answer. You can also run the code online. If you are interested in algorithm see wikibooks. Help is welcome. More code is for parameter plane. . --Adam majewski (talk) 10:23, 28 January 2017 (UTC)

Yest it works without that line. See new code. To answer more about algorithm I need to learn it because it was some tome ago. If you are interested let me know. HTH --Adam majewski (talk) 11:14, 28 January 2017 (UTC)

Thanks. I see that the move to w-plane happens inside Phi_n() so the line I mentioned is unnecessary. Can I thank you here for all the resources you have posted on-line, in particular your useful site 'fraktal republika'. I am puzzled by the significance of the -1/7,-2/7 and -4/7 rays all of which land?(refering to JuliaRay3.png here). I'm looking into this. 31.48.216.195 12:57, 28 January 2017 (UTC)p borthwick

You mean symbolic dynamics, invariant laminations, .... Look also here. It is a code which I plan to translate to dynamic plane.
