作者: 柳烟 时间: 2016-8-18 22:08 标题: UF与GSP合研复分形

这是此坛大家讨论过的复分形，以前看大家的讨论帖子，似懂非懂。现在再研究之，由迷糊到清晰，有些收获，今放到此，望起到抛砖引玉的作用。

复合函数的零点确定很有规律，都能通过放大大M后找到小M。#6楼，函数f(z)=(1-z^2)/(z-z^2cos(z))的导数f'(z)的任一零点均可。另函数f(z)+c=0的零点也可以。
用maple算出f'(z)的一个复根为：

将#6代码中的z的初始值由z=1.5445654699195换成z=(-1.108647299,-.8001950999),仍能扫出标致的小M，十分漂亮。

用GSP多算几个零点，先用maple求出函数的一阶导数，再在GSP中作出该函数，找出x轴交点，再用高精坐标工具找出函数的零点。

The two programs can be copied and inserted in an empty formula and colouring document, respectively. We have inserted the polynomial {\displaystyle z^{2}/2+p*z^{4}+c} {\displaystyle z^{2}/2+p*z^{4}+c} of degree 4, where p is a real parameter. The picture shows a section of the Mandelbrot set for p = 0.26.

UF中打开是黑的，说明用et调色不行了，要用其它调色法才能出现分形图形。
网上分形1000(1-z)/(8-4z+2z^2-z^3)+c的J集就是如此。

Nova (Mandelbrot),z-f(z)/f'(z)+c应定位于z-f(z)/f'(z)+c的导函数为零的点，这样才能扫出标准的M集。

这是f(z)=z^3-1的此种分形。

好象也可定位为f(z)的零点，我正在UF中尝试，大家可研究看看。

此是复合函数，定位于z=0或者z=sqrt(1-c)或z=-sqrt(1-c)或者z=sqrt(－0.5-.866025403784439I-c)或者z=sqrt(－0.5-.866025403784439I-c)
