How to save a figure through each run of a for loop?

Hello,
I am running a for loop:
for i=1:5
and in each loop, I am creating and saving a plot:
h=figure
plot(...)
saveas(h,'FIG','png');
end
This is problematic because 'FIG.png' is overwritten each time the for loop runs. How do I make it so that it saves 'FIG1.png','FIG2.png','FIG3.png', etc? In other words, how do I save FIG(i).png?
Thank you for your time.

for k=1:5
h=figure
plot(...)
saveas(h,sprintf('FIG%d.png',k)); % will create FIG1, FIG2,...
end

If you have r2020a or later, try exportgraphics().

You can try this,
for i=1:3
.
.
for k=1:5
h=figure;
plot(..);
fig_name = strcat('FIG_',num2str(i),'_',num2str(k));
print(h,fig_name,'-dpng','-r400');
end
end
This way you can print to your desired format and resolution.
