i am not getting chaotic plot because of warning

function dx = compactchua(t,x)

dx=zeros(4,1);

dx(1) = -(1/(8200*47*1e-9))*x(2);

dx(2) = (((x(3)-x(2))/2000) -(x(4).^3*4.7e3+1e3))/6.8e-9;

dx(3) = ((x(2)-x(3))/2000 - x(4))/68e-9;

dx(4) = (x(3))/(22*10^-9);

end

[t,x] = ode15s(@compactchua,[0 5e-7],[0 12.24e-3 12.24e-3 1.7]);

plot(x(:,2),x(:,3));

error

Warning: Failure at t=6.943264e-08. Unable to meet integration tolerances without reducing the step size below

the smallest value allowed (2.117582e-22) at time t.

[Benjamin Thompson]

Chaotic systems have behavior that is not well described using continuous and differentiable functions right? So a solver that attempts to reduce step size until it finds continuous and predictable differentiation results is probably not going to work there. Have you tried one of the other solvers to see if results are better?
