For some expressions of x_k, y_k, E_k, why the error "Value must be a handle" is copming for the follwing code:
figure(1)
sub1=subplot(2,1,1);
ani1 = animatedline('Color','r');
sub2 = subplot(2,1,2);
ani2 = animatedline('Color','k');
for k=1:length(t)
t_k = t(k);
x_k = x(k);
y_k = y(k);
E_k = E(k);
plot(x_k, y_k,'go','LineWidth',1.5,'MarkerSize',2)
hold on
title(['Time=',num2str(k*0.01)]);
addpoints(ani1,x,y);
plot(t_k, E_k,'go','LineWidth',1.5,'MarkerSize',2)
hold on
addpoints(ani2,t, E(1:end-1));
drawnow
end
Can anyone plz help?
