Hello,

 

I am a new fellow of maple software.

 

I am trying to run an example of Poincare package example found in 

http://www.maplesoft.com/support/help/maple/view.aspx?path=examples%2Fpoincare

But when i  wrote the commands found in this site, i got this error:  Error, unable to match delimiters 

The commands  are the following:

> restart;
> with(DEtools, poincare, generate_ic, zoom, hamilton_eqs);
> H := ((p1^2+p2^2)*(1/2))*((e^(2*q2+2*sqrt(3)*q1)+e^(2*q2-2*sqrt(3)*q1)+e^(-4*q2))*(1/24))-1/8;

 

> poincare('' '', stepsize=.05,iterations=5);
Error, unable to match delimiters 

                                        poincare('' '', stepsize=.05,iterations=5)

I would appreciate any helps.

 

Miguel
