GingerBread_Man iterated chaotic map with parameters. Attractor explorer.

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:
