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

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?
