Solving Differential Equation

[eric_h22]

Hi, my name is Eric, a newbie to Octave.

Im using octave to solve this ode:
xdot(1)=x(2);
xdot(2)=x(1)+x(1)^3;
with
x0=[1;1];
t=linspace(0,500,1000)

I'm using lsode to solve it. I got an error:
LSODE-- WARNING..INTERVAL T (=R1) AND H(=R2) ARE SUCH THAT IN THE MACHINE
T+H=T ON THE NEXT STEP (H=STEP SIZE). SOLVER WILL CONTINUE ANYWAY

error:lsode: excess work on this call (t=1.530358; perhaps wrong integration
method)

Can someone help me?

Thx.
