Here, I have a 3D map T=(T1,T2,T3) with

T1(x1,x2,x3)=x1*exp(6-2*x1-x2-0.3*x3),

T2(x1,x2,x3)=x2*exp(5-2*x1-2*x2-*x3),

T3(x1,x2,x3)=x3*exp(8-0.2*x1-x2-x3),

How can I use  IterativeMaps:-Attractor obtain the attractor for T.

How do I simulate the follow stochastic differential equations. Thanks very much!

dx=x*(5-2*x-3*y-z)dt+5x*dB1(t);

dy=y*(4-*x-5*y-2z)dt+4y*dB2(t);

dz=z*(2-5*x-7*y-2z)dt+2z*dB3(t);

How can I embedded a Maple program in Powerpoint to show it. Does there is a Powerponit plugin for maple?

How to use IterativeMaps:-Bifurcation for two or more dimensional maps. For example, f(x,y)=x*exp(r1*(1-a11*x-a12*y)), g(x,y)=y*exp(r2*(1-a21*x-a22*y)).

If I set a11=1,a12=2,a21=3,a22=4,r2=1, then how can I get the bifurcation rsp r1. Thanks very much!

with(IterativeMaps);
with(ImageTools);
Logistic := Bifurcation([x], [r*x*(1-x)], [.5], 2.5, 4);
ArrayTools:-Dimensions(Logistic);
ColouringProcedures:-HueToRGB(Logistic);
Embed(Logistic);

This is the code for Bifurcation program of the Logistic map. How can I change the black background color of this figure, and How can I save this figure.
