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?

在 MATLAB Online 中打开

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