option=odeset('RelTol', 1e-4, 'AbsTol', 1e-4);
sol = dde23(@syst,[tau],@hystory,[0 2000],option);
figure(1);plot(sol.x,sol.y(1,:)); hold on
xlabel('time t');
ylabel('Displacement [rad]');
I have something like this. Basically, sol.y(1,:) contains displacement values at each sampled time instant. I want to put a condition that if sol.y(1,:) exceeds certain value during the simulation then the system is diverging, otherwise converging. But when I write sol.y(1,:) in the command line MATLAB says: "unknown function"

The question is not clear yet. Does the posted code exist inside a function? Then export the variable sol as output, if you really need it in the command window. Instead of working inside the command window, you could write the code inside the function.

If you want to stop the solution process once one of the components exceeds a certain value, use an Events function (see the Event location section of that documentation page.)
