Hi,

Please can someone help me with a sample code for bifurcation? You can use parameter values for the parameters. I'm using maple 18. Below is my model:

f__1 := Delta -(psi + mu)*S(t);

Delta-(psi+mu)*S(t)

 (1)
> 

f__2 := psi*S(t) -(delta + mu)*E(t);

psi*S(t)-(delta+mu)*E(t)

 (2)
> 

f__3 := Delta*E(t) -(gamma+gamma__1 + mu)*X(t);

Delta*E(t)-(gamma+gamma__1+mu)*X(t)

 (3)
> 

f__4 := gamma__1*X(t)-(eta + xi + mu)*H(t);

gamma__1*X(t)-(eta+xi+mu)*H(t)

 (4)
> 

f__5 := xi*H(t) - mu*R(t);

xi*H(t)-mu*R(t)

 (5)
> 

f__6 := gamma*X(t)-eta*H(t) - d*D(t);

gamma*X(t)-eta*H(t)-d*D(t)

 (6)
> 

f__7 := b*D(t) - b*B(t);

b*D(t)-b*B(t)

 (7)
> 

f__8 := phi__p + sigma*X(t)+eta__1*H(t) +d__1*D(t)+ b__1*B(t) - alpha*P(t);

phi__p+sigma*X(t)+eta__1*H(t)+d__1*D(t)+b__1*B(t)-alpha*P(t)
