I'm using
while
drawnow;hold off
end
to create an animation. But this animation is just the 6th position as in subplot(2,3,6) (or through next tile repeatedly). To save this animation to the computer while not keeping the other subplots 1~5, what to do?

??
That is an infinite loop. Inside the infinite loop, you request that the graphics queue be flushed, and you turn off hold . But you do not do anything else -- no drawing at all, no recording of previously drawn material.
It is not clear what you are trying to do?

thanks for your answer. I omitted '%draw something' as in your code

ax6 = subplot(2,3,6);
count = 0;
while true
%draw something
count = count + 1;
filename = fullfile(SAVEDIRECTORY, "image" + count + ".png");
exportgraphics(ax6, filename);
end

good to hear that. Then how does ax6 = subplot(2,3,6) get in without exportgraphics()?

You have getframe(gcf) which captures the image of the entire current figure.
Note that you could also getframe(ax6) if you wanted to capture subplot(2,3,6) only.
