%How to change the colors in the plot? %I have four curves, and they are black and blue,
%I'm trying to change the color to make it understandable.
plot(tt,xx(:,1),tt,xx(:,2));
grid on
xlabel('time')
ylabel ('Theta')
hold on
plot(ta,xa(:,1),ta,xa(:,2));
legend('theta(position 1)','thetadot(Velocity 1)','theta(position 2)','thetadot(Velocity 2)');
