The orginal question was (paraphrased), "How do I put a blinking circle on a plot".

在 MATLAB Online 中打开

Something like this is a possibility:

plot(1:5);
hcirc=drawcircle;
while 1
    
    hcirc.Visible='on';
    pause(0.2);
    hcirc.Visible='off';
    pause(0.2);
    
end

Did you enter a "center" containing 2 values and a radius? It's difficult to help you when we don't have any information about what might be causing the problem. What's line 4? What inputs did you provide?

I inputted the exact code above and clicked run, then I got an error stating that there is not enough input information in the "x=" part of the function.
