plot trajectory around fix points

hi

i want to plot trajectory around fix point for :

by thanks to Mischa Kim and how to draw a trajectory

if true
  tspan=[0,1.5];
IC = 1.1 + (-1.1-1.1).*rand(300,2);
hold on
for ii = 1:length(IC(:,1))
[t,x]=ode45(@simple1,tspan,IC(ii,:));
plot(x(:,1),x(:,2),'r');
end
title('CE4-3 Trajectory XY')
xlabel('X')
ylabel('Y')
grid
end

and

if true
   function xprime = simple1(t,x);
xprime=[x(2)^2+x(1)*x(2);x(2)^2 - x(2)*x(1)^3];
end
end

but my trajectory looks half .

The differential equations you use to call on 'ode45' don't seem to match the ones you show in your equation picture.

i fix that

function xprime = simple1(t,x);

xprime=[x(1)^2+x(1)*x(2);x(2)^2 - x(2)*x(1)^3]; end

It still doesn't match! There is a minus sign which isn't present in the equation picture.
