clear all
t=0:0.1:2;
figure(1)
plot(t,sin(t))

i run a code which takes several minutes , so in middle i stopped. after that i am getting such type of error for the code which i allready get results (plot)

[KSSV]

The code which you gave should not take much time. Is the attched code,you gave plotting?

[sudhir sa]

No sir, another code. the code attached here is only for testifying

[KSSV]

Then you should show us the code, which you gives you error.

[sudhir sa]

not for a single code but for all the code for which i already got the plot , now showing similar error which i hav mentioned above. the same code is running and also giving plot on online matlab platform.

Hello,

It is my understanding that plot function is not working in your case, and you are receiving the mentioned error.

To fix the error you can insert the plotting code inside if block as:

clc
clear all

figure;
t=0:0.1:2;
g = groot;
fig = get(groot, 'CurrentFigure');
if ~isempty(fig) % true if there are no open graphics objects, false otherwise
    % code to plot
    plot(t,sin(t));
end
