%This is the short routine that calculates the Mandelbrot set
% Parameter Usage
% This function calculates the mandelbrot set within the limits of 
% lowerR higher R lowerI and higherI
% stepsR stepI maxiter define the image resolution, higher settings mean
% better resolution and more CPU time.
% Colormap ranges from 1-18 and defines the look of the result
% viewPoint: 2 or 3 -> 2 or 3D output
% x_view, y_view: 0-360 define the viewing angle of 3D graphs
% myLight: 1-4; defines the lighting effects used for the graph

% Example 
% [x, y, Zvalues ]=dummy2 (-2,2,-2,2,500,700,25,15,3,29,72,3);
% Example increase MaxIter
% [x, y, Zvalues ]=dummy2 (-2,2,-2,2,500,700,100,15,3,29,72,3);
% Example zoom into mandelbrot Set
% [x, y, Zvalues ]=dummy2 (-1.9,0.8,-1.3,1.28,500,700,100,15,3,29,72,3);
