File Information
Description

ginger Is a function for plot gingerBread map [1] [2] [3].

The gingerbreadman map is given by the trnasformation:

        (1)
  x(i) = 1 - a*y(i-1) + b*abs(x(i-1));
  y(i) =x(i-1);
                    
In original form a=1 and b=1. here we can change these parameters to explore diferent atractors.
 
 INPUTS:
       a = This is the a parameter on ecuation (1)
       b = This is the b parameter on ecuation (1)
       numiterations = This set the number of iterations of ecuation (1)
       

 Example (1):

   ginger(1.40,1,10000)

 Example (2):

   We can take frames and create a movie showing the evolution
   
  for i=1:1500
    ginger(2*(i-1)/1500,1,2000)
    axis([-20,20,-20,20])
    M(i)=getframe(gcf)
  end
 
  movie(M)

I uploaded that movie to youtube:

Just change in name to make it more exact and to people looking for it more simple to find it.
