Lets you easily zoom into Mandelbrot set (2D/3D)
Updated 30 Oct 2008

This program uses a vectorised Mandelbrot algorithm (a pretty fast algorithm from Lucio Andrade-Cetto which worked great for me.) I tried before the Fractal Explorer from Laurant Cavin, but that program was not running on my computer and I couldn’t move the GUI to a location where it was useful.

% Usage
Example: type mandel120 in the command line and your Mandelbrot Explorer will start. The program will start it does not
require any parameters and the GUI transfers all parameters
automatically to its sub routines.

Examples: The program starts by loading the mandelbrot set which is stored as mat files x.mat, y.mat and Zvalues.mat

% The program lets you zoom easily into the Mandelbrot Set by just
selecting a subset of the currently displayed graph and then press
the Command Button "Apply Zoom to MandelBrot set" and the new
calcualtion will be performed.

3D views of the Mandelbrot set are easily created by clicked the 3D
pushbutton, 3D Rotate, or one of the 2 sliders that allow to alter
the view ing point of the Mandelbrot set.

The Mandelbrot set contains 3 custom colormaps that will generally
suit Mandelbrot set more than the existing standard repertoire of

Changes since the last version:

Textboxes are now updated in the textbox update_function, which
reduces the amount redundant code in the main script.

Added examples help lines to the code.

Added Colormap editor. Unfortunately, I don't know how to save new colormaps from a GUI. Any thoughts?

Improved aspect ratio when zooming into Mandelbrot Set.

Included a section with stored Mandelbrot Sets (so far one, but more are to come).

I will try to add more functions to the GUI and to improve the
